That pain that starts in the lower back and runs through the buttock, thigh, and leg all the way to the foot, sometimes with tingling or a feeling like an electric shock, has a very familiar name: sciatica. It is one of the most common complaints in the clinic and also one of the things people search for most online, especially when the pain keeps coming back or just won't go away. In this article we explain what sciatica actually is, why it happens, when to see a doctor, and how acupuncture and other Traditional Chinese Medicine techniques, such as cupping, can support you through the process, always as a complement to medical follow-up.
What is sciatica?
Sciatica is not a disease in itself but a symptom: pain that follows the path of the sciatic nerve, the longest nerve in the human body. This nerve leaves the lower part of the spine, passes through the pelvis, runs down the back of the thigh, and branches to reach the leg and foot.
That is why sciatic pain doesn't stay in one place: it usually starts in the lower back or buttock and travels down, sometimes only as far as the thigh and other times all the way to the sole of the foot or the toes. Other sensations commonly come with it:
Tingling, stabbing pain, or burning in the leg.
Weakness: a feeling that the leg "doesn't respond" the way it used to.
Worsening when you cough, sneeze, or sit for a long time.
It is important not to self-diagnose. Low back pain that travels down the leg very often has its cause in the sciatic nerve, but only a doctor can confirm the origin through a proper examination and, if they see fit, additional tests.
Why does my sciatic nerve hurt? The most common causes
The sciatic nerve becomes irritated when something presses on, compresses, or inflames the area it passes through. The most common causes are the following:
Herniated disc
Between each pair of vertebrae there are "cushions" called discs, which absorb the impact of movement. If the contents of one of these discs shift and bulge out of place, they can press on the root of the sciatic nerve and cause pain that runs down the leg. It is the best-known cause and one of the most frequent in young and middle-aged adults.
Muscle tightness
The muscles of the lower back, the pelvis, and the outer side of the buttock can stay tense for long periods because of stress, overexertion, cold, or poor posture. When those muscles stay "hard" for weeks, they compress and irritate the nerve and produce symptoms very similar to those of a herniated disc, even if the structure of the spine is fine.
Sitting for many hours
Working seated for eight, nine, or ten hours with few breaks is one of the causes that has grown the most in recent years. When you sit, the pelvis tilts backward and the lower back either flattens or arches too much depending on your posture, which overloads the lumbar area. In addition, the hip and buttock muscles stay inactive and shorten. The combination of all this promotes irritation of the nerve.
Other causes
Sciatic symptoms can also be caused by degeneration of the joints of the spine (known as lumbar osteoarthritis), stenosis of the canal through which the nerves pass, pregnancy (because of the added weight and changes in posture), or, less frequently, other conditions that only a doctor can evaluate. That is why we insist: your first visit should always be to a doctor.
And what about "false sciatica"?
Sometimes the pain running down the leg does not come from compression in the spine but from a deep muscle in the buttock (the piriformis) that tightens and presses on the sciatic nerve as it passes through the pelvis. This is what is popularly called false sciatica or piriformis syndrome: the symptoms are very similar to those of sciatica caused by a herniated disc, but the origin is muscular, not vertebral. Only a medical examination can tell them apart with certainty, although it often responds well to stretching, deep massage, and acupuncture directed at that area.
When should I see a doctor?
Back pain that runs down the leg should be evaluated by a health professional, especially if it lasts more than a few days or keeps coming back. Seek care promptly if any of these warning signs appear:
Clear loss of strength in the leg or difficulty walking.
Changes in bladder or bowel control.
Pain after a blow or a fall.
Fever or unexplained weight loss along with the pain.
Tingling or loss of sensation that doesn't go away.
These signs are not common, but they require immediate evaluation. In all other cases, the usual course is for the doctor to confirm the diagnosis, rule out serious causes, and propose a treatment based on medication, physical therapy, and postural habits, since most cases of sciatica improve over time with appropriate management.
Which specialist treats sciatica?
The entry point is your family doctor or primary care physician. They examine your back and leg, check strength, reflexes, and sensation, and decide whether imaging tests are needed. If the pain doesn't improve or there are worrying signs, they may refer you to an orthopedic specialist, who deals with the spine and its joints; to a neurologist, when it is useful to study nerve damage; or to a pain unit if the problem drags on. In cases with significant compression that doesn't respond to treatment, the evaluation may move on to a neurosurgeon.
The physical therapist is another key player: they teach the exercises, work on the musculature, and help you recover movement. The acupuncturist comes in as a complement, once the doctor has ruled out serious causes, and it helps if they know what your diagnosis is.
Sciatica in both legs
It is most common for sciatica to affect just one side, because the compression usually occurs at a single nerve root. When pain, tingling, or weakness appear in both legs at the same time, the cause may be a narrowing of the lumbar canal, a larger herniation, or other problems that should be investigated without delay. It is not a cause for alarm on its own, but it does call for a prompt medical consultation, and for the emergency room if it comes with numbness in the genital area or changes in urination or bowel movements.
Sciatica: symptoms and treatment step by step
When pain runs down your leg, the first thing is to understand what is happening to you and what options you have. Here we bring together the essentials on the symptoms, medications, and remedies that usually form part of sciatica treatment.
Sciatica symptoms worth recognizing
Besides the pain that runs through the buttock and the back or side of the leg, sciatica usually brings a series of recognizable problems:
Pain on one side of the body only, more intense in the leg than in the back.
A cramping sensation or electric shock when you move, cough, or bend over.
Difficulty sitting for long periods or finding a comfortable position in bed.
Stiffness when you get up in the morning, which improves a little as you walk.
These symptoms offer clues, but they do not replace a medical examination, which is what makes it possible to know where the irritation of the nerve is coming from.
Medications for sciatica: what to take and who decides
It is one of the most common questions: what to take for sciatica when the pain keeps you awake. Doctors usually turn to painkillers, anti-inflammatories, and, in some cases, muscle relaxants or other drugs specific to nerve pain. The choice, the dose, and the duration depend on your age, other conditions, and the medication you already take, so a professional should always prescribe them. It is best not to self-medicate for weeks or combine drugs on your own, especially if you take anticoagulants, have stomach problems, or are pregnant.
Exercises and home remedies for sciatica
Along with medication, the most useful remedies are usually the simplest ones: gentle local heat on the lower back and buttock, frequent movement instead of complete rest, and the exercises your physical therapist recommends. The most common are pelvic mobility lying on your back, a gentle buttock stretch bringing the knee toward the chest, and short walks several times a day. The rule is the same as in the postural advice: if an exercise makes the pain travel farther down the leg, stop.
Sciatica injections and ointments: when they are used
When the pain is very intense, the doctor may opt for an injectable medication for sciatica, usually an anti-inflammatory or a painkiller that acts faster than pills, and in some cases combined with other drugs. For sciatica that drags on and doesn't respond, there are also injections near the nerve root, performed by a specialist in the pain unit or in orthopedics after reviewing the test results. These are medical decisions: it is not a good idea to ask for an injection "just to get by" without a prior examination.
Ointments for sciatica, such as anti-inflammatory ones or those with a cooling or warming effect, relieve mainly the muscular and superficial part of the pain, the tightness in the lower back and buttock, but they do not reach the compressed nerve. They can be a good complement, applied with a gentle massage, always on healthy skin and without combining them with intense heat.
Lumbar sciatica exercises at home, also for older adults
A simple routine to do at home, once or twice a day and without rushing, could be this:
Lying on your back with your knees bent, flatten your lower back against the floor and release it, ten times, in rhythm with your breathing.
In the same position, let both knees drop together to one side and then the other, without forcing.
Bring one knee to your chest with the help of your hands, hold for twenty seconds, and switch legs.
Finish by walking around the house for a few minutes.
For older adults, the prudent approach is to adapt the same movements: do them seated in a firm chair or on the bed if getting down on the floor is difficult, lift alternate knees while seated, and always hold on to something stable when standing up. With osteoporosis, a hip replacement, or balance problems, the physical therapist should indicate which exercises are appropriate.
Lumbar massage and sciatica
Massage of the lower back and buttock can loosen the muscles surrounding the nerve, especially when there is a component of muscle tightness or false sciatica. In Chinese medicine, tuina is used, a therapeutic massage that follows the Bladder and Gallbladder channels (meridians) along the back and leg. In the most acute phase, or if a herniated disc has been diagnosed, the massage should be gentle and should never press hard on the spine.
How long does sciatica last, and how long can sick leave last?
The question of whether sciatica goes away has, in most cases, a reassuring answer: intense pain usually calms down within a few weeks and improvement continues over the following months, although every case is different. The cause, age, and how soon you resume movement all weigh on the outcome.
The length of sick leave for sciatica is not set in advance. The doctor decides it based on the intensity of the pain, the loss of strength, and above all the type of work: it is not the same to spend the day at a computer, where adapting the workstation is sometimes enough, as to carry heavy loads or drive for many hours. During sick leave, absolute bed rest doesn't help; it is best to move within what you can tolerate, follow the treatment, and return to work gradually when the doctor considers it appropriate.
Can sciatica be cured naturally and for good?
It is the question that comes up most, and it deserves an honest answer. Many cases of sciatica improve on their own in weeks or months, because the body reabsorbs part of the herniation or the inflammation of the nerve settles down. Natural measures help most in that process: moving regularly, local heat, sleeping well, losing weight if there is overload, and strengthening the abdominal and hip muscles, which act as a built-in support belt for the spine. No one can promise, however, that the pain will never return: what does reduce relapses is keeping up those habits once you are feeling well.
Among the most sensible home remedies for sciatica are a hot water bottle or an electric blanket at a moderate temperature for fifteen or twenty minutes, short and frequent walks, and the gentle acupressure of the points we explain below. If the pain is linked to cold, Chinese medicine adds acupressure of Shenshu (BL23), two finger-widths from the spine at waist level, and of Dachangshu (BL25), a little lower, at the level of the iliac crest. Infusions, ointments, or supplements advertised as miraculous do not replace treatment, and any medicinal herb or Chinese formula should be prescribed by a professional, especially if you already take medication.
Sciatica in Chinese medicine
Traditional Chinese Medicine describes sciatica as a blockage of qi, the vital energy that, according to this tradition, flows through the body, and of Blood in the channels that run down the leg, especially the Bladder channel at the back and the Gallbladder channel along the side. That blockage is related to the invasion of Cold and Dampness, to overexertion, or to a weakening of Kidney Qi, which in this view supports the lower back.
That is why, in addition to acupuncture and cupping, the practitioner may suggest other techniques:
Moxibustion: heat from mugwort applied near the skin, useful when the pain gets worse with cold and damp.
Auricular therapy: stimulation of points on the ear related to the lower back and the sciatic nerve, as support between sessions.
Tai chi and qigong: slow movements and breathing that keep the hip and back mobile without abruptness, better suited once the acute phase has passed.
One point that is often added to those used in acupressure is Kunlun (BL60), behind the outer ankle, between the bone and the Achilles tendon, a classic for lower back pain that reaches the foot. It is not pressed during pregnancy.
Moxibustion for sciatica
Moxibustion makes the most sense for the kind of sciatica that Chinese medicine calls the cold type: the pain gets worse in damp weather, the lower back feels cold, and heat brings relief. The practitioner brings a lit mugwort stick close to points on the back such as Mingmen (GV4), between the lumbar vertebrae at waist level, or Yaoyangguan (GV3), a little lower, and sometimes over points on the leg. It is not applied to skin with loss of sensation, because of the risk of burns, or to the lower back during pregnancy.
How does acupuncture support recovery?
Acupuncture is an ancient technique of Traditional Chinese Medicine that consists of inserting very fine needles at specific points on the body. It is not magic or a miracle remedy: it is understood as one more tool within a comprehensive approach to pain, and never as a substitute for medical diagnosis or treatment.
From the Western perspective, acupuncture has been studied for decades as a complement in managing low back pain and musculoskeletal pain. It is considered that stimulating the points may modulate the perception of pain and promote relaxation of the tissues. From the perspective of Chinese medicine, pain appears when energy and circulation do not flow freely; acupuncture seeks to restore that balance so that the area works harmoniously again.
In the case of sciatica, acupuncture is usually applied to the lower back, buttocks, and leg, always adapted to each person, to the intensity of the pain, and to the phase they are in (acute or more chronic). People who come to the clinic often describe a feeling of relief and release, often from the first sessions, although progress is individual and results cannot be guaranteed.
The WHO recognizes acupuncture as a traditional practice with widespread use, and research is ongoing on its role as support in chronic pain. If you are thinking about trying it, do so with a qualified professional and tell the doctor who is following your case, so that the whole team is coordinated.
And what does cupping add?
Cupping uses cups, usually made of glass or silicone, that attach to the skin by suction. In Chinese medicine they have been used for centuries to promote circulation and relieve tension in the deep muscles of the back.
In areas such as the lower back or buttocks, where many cases of sciatica have a significant muscle-tightness component, cupping can be an interesting complement to acupuncture. Some people feel the area looser and under less pressure after the session. It isn't painful, although it usually leaves circular marks that fade within several days.
Like acupuncture, cupping is used as support and should never be applied over skin lesions or replace the treatment prescribed by your doctor.
Acupressure for sciatica: points you can try at home
Between sessions, acupressure—pressing with your finger, without needles—on a few classic points can bring gentle relief:
Huantiao (GB30), "Circle Jump": in the center of the buttock, at the most prominent spot when you squeeze the muscle. It is the traditional reference point for sciatic and hip pain.
Weizhong (BL40), in the center of the crease behind the knee: a classic for pain that runs down the back of the leg.
Yanglingquan (GB34), on the outer side of the leg, below the head of the fibula: useful when the pain follows the side of the thigh and leg.
Press with gentle firmness for one or two minutes on each point, breathing slowly, and never to the point of sharp pain. If there is loss of strength, tingling that doesn't go away, or the pain gets worse, acupressure is not enough: it is time for a medical evaluation.
Posture tips and safe mobility for everyday life
What you do every day matters as much as what you do in the clinic. These habits can help you avoid overloading the area and support your recovery:
Break up long hours of sitting: stand up for two or three minutes every half hour, even if it's just to go to the bathroom or stretch your legs.
Check your chair: your feet should rest on the floor, your knees at or slightly below hip level, and your lower back supported.
Avoid carrying weight on one side only: spread the backpack across both straps and don't always carry it on the same shoulder.
When lifting objects from the floor, bend your knees and keep your back straight, holding the weight close to your body.
Choose comfortable footwear and avoid very high heels during painful periods.
Keep up gentle, regular movement: walking, swimming, or gentle back and hip stretches, adapted to your situation and best assessed with a professional.
In bed, try sleeping on your side with your knees slightly bent and a pillow between your legs, which often eases lower back tension.
Remember that in the acute phase you should not force stretches or make sudden movements. The general rule is that no exercise should increase the pain or make it travel farther down the leg.
Frequently asked questions
Does acupuncture cure sciatica?
It isn't accurate to talk about a cure. Acupuncture can help ease the perception of pain, promote muscle relaxation, and support the recovery process, but always as a complement to medical diagnosis and treatment, and without guaranteeing results in every case.
Can sciatica be cured, or does it always come back?
Most cases of sciatica improve within weeks or a few months with medical treatment, movement, and good habits, and many people end up with no symptoms. In other cases the pain returns during periods of overload, which is why taking care of your posture, staying active, and strengthening your back helps prevent relapses. Your doctor is the one who can advise you on the expected course in your case.
Why does sciatica happen?
It happens when something compresses or irritates the sciatic nerve along its path: often a herniated disc, but also lumbar osteoarthritis, narrowing of the spinal canal, or a tight buttock muscle. Sitting for many hours, lifting weight abruptly, excess weight, and pregnancy make it more likely to appear. In Chinese medicine, Cold, Dampness, and depletion of Kidney Qi also play a part.
Which sciatica exercises are safe at the beginning?
In the painful phase, the most prudent are the gentle ones: walking in short stretches, rocking the pelvis lying on your back, and calmly bringing one knee toward the chest. When the pain eases, the physical therapist usually adds exercises to strengthen the abdomen and glutes, and tai chi or qigong help keep the hip mobile. Any exercise that makes the pain travel down the leg should be stopped.
How long does sick leave for sciatica last?
It depends on the pain, the loss of strength, and the work you do, and the doctor sets it in each case. Jobs involving heavy loads or many hours of driving usually require more time than sedentary ones. Staying active within what you can tolerate and following the treatment supports a gradual return.
How many acupuncture sessions are usually needed?
It depends on the person, the cause of the pain, and how long it has been present. Many people notice changes in the first sessions, while others need a longer process. A qualified professional will assess your case and advise you on the most appropriate frequency.
Does acupuncture hurt?
The needles are extremely thin, much thinner than those used for drawing blood, and what's typical is a slight sensation of pressure or a brief little twinge on insertion, which passes right away. Most people relax during the session.
Can I have acupuncture if I have a herniated disc?
Yes, as long as your doctor doesn't advise against it. Acupuncture doesn't act on the herniation itself; rather, it seeks to support the management of the associated pain and tension. It is important to tell your acupuncturist about your diagnosis and any tests you have had.
Is cupping safe?
When it is performed by a qualified professional and there are no skin lesions or medical contraindications, cupping is a well-tolerated technique. It leaves temporary marks lasting from one to several days, which are normal and should not be confused with bruises.
See a qualified professional
Sciatica can improve in most cases, but it is best approached with patience, good habits, and the right support. If pain is running down your leg, start with a medical evaluation and, if you are interested in complementing the process with acupuncture or cupping, always look for properly trained professionals who work in coordination with your doctor. Your back will thank you.
