There's a pain that shows up in an almost funny way the first time: you reach for a coffee cup, open a door, or tighten a screw, and a sharp pain shoots through the outer side of your elbow like an electric shock. You clench your fist to check, and it hurts. You grab the steering wheel, and it hurts. Even typing at the computer starts to feel uncomfortable. Welcome to tennis elbow, one of the most common elbow problems in the world… and one of the most mistreated by its own name, because the vast majority of people who have it have never picked up a racket in their lives.
Its medical name is lateral epicondylitis, and it affects office workers, plumbers, painters, cooks, gardeners, parents of small children (yes, carrying babies counts too) and, of course, athletes. If pain on the outer side of your elbow has been nagging at you, this article is for you: what exactly it is, why it takes so long to heal, and what acupuncture can offer.
What is tennis elbow?
On the outer side of the elbow there's a small bony bump: the lateral epicondyle. The tendons that connect the extensor muscles of the forearm to the bone—the ones you use to extend your wrist and fingers—start there. Those tendons are what let you hold a racket, make a fist, turn a key, or hold your phone, among many other things.
Tennis elbow is an overload of those tendons: tiny tears and tissue degeneration caused by repeated movements or excessive loads. Lifting weight with the wrist extended, repeating gripping and rotating motions, using vibrating tools, or using a computer mouse for hours are the classic triggers. The tendon gets irritated, becomes inflamed, and—this is key—its blood supply is poor, which explains its reputation for slow healing: tendons receive little blood and repair themselves slowly.
The typical symptoms:
Pain on the outer side of the elbow that may radiate down the forearm.
Pain that gets worse when you grip objects, rotate your wrist, or extend your fingers.
Weak grip: you drop things or have trouble opening a jar.
Pain when you press on the epicondyle area.
Discomfort that appears or gets worse with activity and, in chronic cases, may hurt even at rest.
Tennis elbow symptoms in daily life
Rather than constant pain, tennis elbow symptoms tend to show up with very specific movements: lifting a chair or a frying pan with your palm facing down, shaking hands firmly, wringing out a cloth, or carrying a bag with your arm straight. At first the discomfort appears after you finish the activity; over time it arrives earlier and accompanies the movement from the very start. If squeezing your fist with the wrist slightly extended reproduces the pain on the outer side of the elbow, the suspicion is fairly clear, although a professional should make the diagnosis.
Tests and exams for tennis elbow
Diagnosing tennis elbow is mostly clinical: the doctor or physical therapist listens to how the pain began, palpates the epicondyle, and performs a few simple tests that try to reproduce the discomfort by tensing the extensor tendons. The most common ones are these:
Cozen's test: with your elbow bent and your fist closed, you try to lift your wrist while the examiner resists. If it hurts on the outer side of the elbow, the test is positive.
Mill's test: the examiner straightens your elbow while bending your wrist downward and rotating your forearm with the palm facing the floor, which stretches the extensors.
Maudsley's test: you try to lift your middle finger against resistance; pain at the epicondyle points to the injury.
Imaging usually isn't needed at first. Ultrasound can show the condition of the tendon, while X-rays or MRI are reserved for ruling out other causes or for cases that aren't progressing. It's best not to try these tests forcefully at home: they're meant to guide, not to confirm anything on your own.
Causes of tennis elbow and the muscles involved
Tennis elbow doesn't come from a single blow but from accumulation: thousands of small strains on the same tendon without enough time to recover. Among the most common causes of tennis elbow are repetitive gripping and wrist-turning work, prolonged use of the mouse or keyboard with the wrist raised, heavy or vibrating tools, and sudden increases in load, such as taking up a racket sport, moving house, or a stretch of intense gardening. Age also plays a role: it's more common after 35–40, when tendons tolerate overload less well.
Which muscles are involved
The main player is almost always the extensor carpi radialis brevis, a forearm muscle that stabilizes the wrist every time you grab something. Its tendon starts at the epicondyle and is the one that suffers most. Usually involved along with it are the extensor digitorum, the extensor carpi radialis longus, and the supinator, the muscle that rotates the forearm to turn the palm upward. That's why the pain can travel down the outer side of the forearm, and why treatment isn't limited to the spot that hurts: it works on the entire extensor musculature.
What about golfer's elbow, or medial epicondylitis?
Medial epicondylitis is the same injury on the opposite side: the inner side of the elbow hurts, the side toward the pinky, where the muscles that flex the wrist and close the hand attach. It's called golfer's elbow, but it appears just as often in climbers, in people who lift weights with poor technique, or in jobs that require a strong grip. It's less common than lateral epicondylitis and is treated with the same principles: adjusting the load, progressive exercises and, as a complement, acupuncture. Only the local points change: instead of Quchi and Shousanli, the acupuncturist works around the medial epicondyle and on points such as Shaohai (HT3), at the inner end of the elbow crease.
Why it becomes chronic (and why so much treatment fails)
Acute lateral epicondylitis should heal within weeks with relative rest. But there's a basic problem: almost no one can afford real rest. If the pain comes from your job—typing, lifting, tools, serving customers—or from caring for your family, "not using your arm" isn't an option. The tendon keeps working below the pain threshold, gets irritated again before it has healed, and the process drags on for months, sometimes more than a year.
On top of that comes another factor: the area gets little circulation. And this is where the Chinese tradition has something very interesting to say.
What does Traditional Chinese Medicine say about tennis elbow?
The Chinese tradition describes this picture with surprising precision for something described centuries ago: elbow pain that gets worse with use, responds poorly to prolonged rest, and gets worse with cold and dampness. Its interpretation rests on two concepts that fit very well with what modern physiology knows:
Blockage of local circulation: where the circulation of blood and energy doesn't flow freely, tissue is neither nourished nor repaired. A tendon degenerated by overload is, exactly, a poorly supplied tissue that can't manage to repair itself. The tradition describes it as "wind, cold, and dampness have settled in the arm channel": cold and dampness hinder local circulation and "freeze" the area.
Overload of the gripping system: in the traditional view, the gripping and extending muscles are coordinated by a single functional system; when it's overused without enough rest, that system tightens, loses flexibility, and stops nourishing its tendons well.
The traditional therapeutic approach is twofold: on one hand, restoring circulation in the area so the tendon receives blood and can repair itself (hence the combined use of acupuncture and moxibustion—therapeutic heat—and cupping in some protocols); on the other, relaxing the tension in the forearm and the neck-shoulder area, because elbow overload is rarely just about the elbow: it usually comes from a chain of tension that starts in the neck and shoulder. If you have neck muscle knots, tennis elbow feeds on them.
What does science say about acupuncture and epicondylitis?
It's one of the areas where acupuncture has moderate but consistent evidence:
Clinical trials compare acupuncture with anti-inflammatories, corticosteroid injections, or simply waiting, and in several of them acupuncture achieves comparable or better results in pain reduction and functional improvement in the medium term. Interestingly, several studies show that corticosteroid injections win in the short term but lose in the long term (with more relapses), while acupuncture maintains its effect.
Systematic reviews conclude that acupuncture is a reasonable option for chronic epicondylitis, especially in cases that resist conventional treatment, with a very low rate of side effects.
The mechanisms are still being studied: acupuncture is known to release endorphins and modulate pain perception, and its effect on local blood flow and tissue repair is under investigation—precisely what a poorly supplied tendon needs.
Combined treatment with moxibustion (therapeutic heat) has been associated in studies with better results than acupuncture alone in some protocols.
The honest take: acupuncture isn't magic and doesn't replace physical therapy with eccentric exercises (which has the best long-term evidence), but it's a very valuable complementary tool, especially in chronic stages and for people who can't or don't want more medication.
What does acupuncture treatment look like?
The first visit will review your history: which movements trigger the pain, what jobs or hobbies you have, what treatments you've tried, how you sleep, and whether you have tension in the neck and shoulder on the same side. The acupuncturist will palpate the area to locate the exact painful points and will assess the entire chain: neck, shoulder, forearm, and wrist.
Sessions are usually weekly at first (a typical evaluation cycle is 6–10 sessions) and combine:
Local acupuncture in the elbow and forearm: very fine needles around the epicondyle and along the path of the extensor muscles, with classic points such as Quchi (LI11), at the elbow crease, and Shousanli (LI10), two finger-widths below, both on the Large Intestine channel, which runs right through that area.
Moxibustion: therapeutic heat over the area to increase local blood flow. It's the classic complement and is backed by studies.
Points on the neck and shoulder: to release the tension that feeds the overload.
Ergonomic advice: adjusting your mouse, keyboard, sports technique, or use of tools, because without this the tendon gets irritated again.
What can you expect to notice? Improvement is usually gradual: first the pain intensity drops during everyday activities, then your grip improves, and finally the residual discomfort goes away. In chronic epicondylitis of months or years, it's reasonable to expect a process of several weeks: the tendon needs time to repair itself.
How to treat tennis elbow: physical therapy and exercises for epicondylitis
Physical therapy for tennis elbow relies mainly on therapeutic exercise, which the physical therapist usually combines with manual therapy on the forearm and, depending on the case, other techniques. Exercises to improve epicondylitis generally follow a progression:
Isometrics: with your forearm supported, try to extend your wrist while your other hand resists, with no movement, for about 30–45 seconds. They usually calm the pain and are the starting point.
Eccentrics: with a light dumbbell or a water bottle, raise your wrist with the help of your other hand and lower it on its own, very slowly.
Extensor stretching: with your arm straight and palm facing down, gently bend your wrist with the other hand until you feel tension in the forearm, without pain.
Gripping and rotations: squeezing a soft ball and rotating the forearm with a hammer or a light bar round out the work.
The practical rule is that discomfort during the exercises should be mild and shouldn't increase the next day. If it gets worse, reduce the load; don't give up. Alongside this, acupressure at home, moxibustion, and the cupping that the acupuncturist applies to the forearm can help relieve muscle tension and make the exercises easier to tolerate.
What else helps recovery
Eccentric exercises: they're the cornerstone of treatment (physical therapy). They involve lowering loads slowly and in a controlled way with the extensors; they regenerate the tendon with the best evidence available. Your physical therapist will teach them to you.
Adjusting activity, not complete rest: reduce the loads that trigger intense pain, but don't immobilize the arm: prolonged immobilization weakens it and worsens the prognosis.
Computer ergonomics: neutral wrist (neither flexed nor extended), forearm supported, mouse close to your body.
Local heat before activity: a warm heat pack on the elbow and forearm for 10 minutes prepares the tissue.
Local cold after overload: if you've pushed the area too hard, apply cold for 10–15 minutes afterward.
Watch your neck and shoulder: neck tension keeps the elbow problem going; gentle neck and shoulder stretches help.
Acupressure between sessions: press Shousanli, two finger-widths below the elbow crease on the outer side of the forearm, for one or two minutes, with pressure that is a little uncomfortable but not painful. Avoid pressing directly on the epicondyle bone if it's very sensitive; work the forearm muscles, which are the ones pulling on the tendon.
Realistic patience: a chronic tendon improves in weeks to months, not days. Plans of 8–12 weeks are the norm, not the exception.
Can epicondylitis be cured, and how long does it take?
The good news is that yes: epicondylitis tends to resolve in the vast majority of people, though at its own pace. How long it takes depends mainly on three things: how long you've had pain before starting treatment, how much you can reduce the load that causes it, and how consistent you are with the exercises. A recent case of tennis elbow, caught in time, usually improves in a few weeks; one that has been overloaded for months may need several months and, in some cases, more than a year. It isn't a degenerative disease that inevitably gets worse, but a tendon that needs the right conditions to repair itself.
Can tennis elbow be cured quickly?
It's the question everyone asks, and the honest answer is that there are no shortcuts for a tendon to regenerate. What does exist is a way not to prolong it: start early, cut back on the movements that set off the pain without immobilizing the arm, do the exercises your physical therapist prescribes every day, and correct your posture at work. Injections can calm the pain quickly but, as we've seen, they don't speed up repair and are associated with more relapses.
Along the way, Chinese medicine offers tools to bring relief while the tendon repairs itself. Moxibustion on Quchi (LI11) and the epicondyle area provides warmth and promotes local blood flow; cupping over the belly of the extensor muscles helps release forearm tension, and acupressure at home on Shousanli (LI10) and Hegu (LI4) keeps the work going between sessions. None of them replaces the exercises, but they make the exercises easier to tolerate and the process more bearable.
Important precautions
- Elbow pain is not always epicondylitis: it could be radiating neck problems, nerve compression at the elbow (cubital tunnel syndrome), or other causes. If the pain comes with tingling or numbness in the forearm or hand, see your doctor first.
- Acupuncture is a complement, not a substitute for diagnosis or for physical therapy with exercises.
- If you've tried several treatments for more than 6–12 months without improvement, your orthopedic specialist may consider additional options (platelet-rich plasma, surgery in selected cases).
- Tell your acupuncturist if you take anticoagulants.
- Choose professionals with accredited training and sterile, single-use materials.
Frequently asked questions
Does acupuncture cure tennis elbow?
Epicondylitis tends to heal over time in most cases (although it can take anywhere from months to more than a year). What the evidence suggests is that acupuncture—especially combined with moxibustion—can speed up recovery, reduce pain, and improve function, particularly in chronic stages.
How many sessions are needed?
As a guideline, an initial cycle of 6–10 weekly sessions with a reassessment is usually proposed. Many people notice changes between the third and sixth session; long-standing epicondylitis requires more persistence.
I don't play tennis. Can I still get tennis elbow?
Absolutely: most cases occur in people who don't play tennis. Any repetitive gripping and wrist-extending activity—computer work, tools, crafts, carrying babies—can cause it.
Is tennis elbow a serious condition?
No. What's called tennis elbow syndrome is an overuse injury of the extensor tendons, not a systemic or joint disease. It can be very bothersome and limit your work for months, but it doesn't damage the elbow joint and tends to resolve with a well-planned treatment. If the pain is accompanied by significant swelling, fever, tingling, or marked loss of strength, a doctor should evaluate it.
Can cupping be used for tennis elbow?
Yes, as a complement. The acupuncturist usually applies it over the forearm muscles, not on top of the epicondyle bone, to relax the extensors and improve local circulation. It can leave round marks that fade in a few days. It isn't applied over injured skin or very inflamed areas, and if you take anticoagulants you should mention it beforehand.
Which acupressure points are used for tennis elbow?
Besides Shousanli, on the outer side of the forearm, the usual points are Zhouliao (LI12), just above and outside the elbow crease, and Hegu (LI4), between the thumb and index finger. Press each one for one or two minutes with firm but tolerable pressure. Avoid Hegu during pregnancy, and if the area is inflamed or the pain increases, check with a professional first.
Does acupuncture on the elbow hurt?
The area may be sensitive, but the needles are very fine and the technique is gentle. The usual sensation is mild pressure or local warmth; many people feel relief during the session itself.
Can I keep working while I'm being treated?
Yes. In general, the recommendation is to adjust the loads that trigger intense pain but stay active: prolonged complete rest worsens the prognosis. Your physical therapist and your acupuncturist will guide you on how to pace things.
Does moxa (moxibustion) burn?
No: direct moxibustion is applied with precise technique and the sensation is of intense but pleasant warmth; with indirect moxibustion (the most common in the West), the heat is applied from a distance, with no direct contact between the ember and the skin. It should always be applied by a qualified professional.
Conclusion
Tennis elbow is a small problem with a reputation for being stubborn: a poorly supplied tendon, fed by a life that never stops, that heals at its own pace. The formula for beating it is the usual one: a good diagnosis, well-performed physical therapy exercises, load adjustment, and patience—and, if you want to add a tool with good evidence and an excellent safety profile, acupuncture with moxibustion.
If elbow pain has been with you for months, stop waiting for it to go away on its own. A qualified professional can help you shorten that road. And remember: the next time you tighten a screw, do it with a neutral wrist. Your epicondyle will thank you.
