Tennis elbow (lateral epicondylitis) is technically a tendinopathy of the common extensor tendon at the lateral epicondyle of the humerus. In practice, it means pain at the outer elbow that gets worse with gripping, lifting, and rotating the forearm. Despite the name, it's far more common in people who have never held a tennis racket — keyboard and mouse use, power tool operation, and any repetitive gripping motion can trigger it.
In Canada, physiotherapy is first-line treatment and is covered by most extended health plans. However, physiotherapy waitlists can be 4–8 weeks in major centres, and in the meantime the condition can significantly impair daily function. Corticosteroid injections give short-term relief but don't improve long-term outcomes compared to watchful waiting, according to multiple RCTs.
Acupuncture for lateral epicondylitis has meaningful trial evidence. A 2022 Cochrane review found moderate-certainty evidence that acupuncture improved pain and function compared to sham in the short term (4–8 weeks). A 2016 RCT (Tsui et al., Journal of Alternative and Complementary Medicine) found similar outcomes between acupuncture and corticosteroid injection at 12 weeks, with acupuncture showing better maintenance at 52 weeks. This is a condition where the evidence supports giving acupuncture or acupressure a serious trial.
Anatomy That Makes This Work
The Large Intestine meridian runs along the outer forearm and terminates at the index finger. The key points for tennis elbow — LI10, LI11, LI4 — all lie on this pathway. The Triple Energizer meridian (TE/SJ) runs along the back of the forearm and wrist, and TE5 targets that pathway specifically. The combination addresses both the local soft tissue and the referred pain that often spreads up the forearm or into the wrist.
The Points
LI11 / Quchi — Pool at the Bend
Location: At the outer end of the elbow crease when the arm is bent 90°. With your elbow bent, find the outer end of the crease — LI11 is there, in a small depression.
What it does: The he-sea point of the Large Intestine meridian — one of the most important points for clearing inflammation and heat from the meridian. For tennis elbow, LI11 is the primary local point directly over the lateral epicondyle region. It's often extremely tender in active tennis elbow. Apply firm sustained pressure, 60–90 seconds. The tenderness is expected and therapeutic.
LI10 / Shousanli — Arm Three Miles
Location: Two finger-widths below LI11 (further down the forearm toward the wrist), on the radial (thumb) side of the forearm.
What it does: A local forearm point that addresses the extensor muscle belly itself — the muscles that connect to the lateral epicondyle and whose repeated contraction causes the tendinopathy. LI10 is particularly effective for the forearm aching that extends from the elbow down toward the wrist. Apply firm pressure, 60 seconds.
LI4 / Hegu — Union Valley
Location: In the webbing between the thumb and index finger, at the peak of the muscle mound when you bring them together.
What it does: The major distal point for the Large Intestine meridian and the hand/forearm region generally. LI4 provides analgesic effect through the whole meridian pathway — from the index finger up through the forearm to the elbow. It amplifies the effect of the local points above. Apply firm pressure, 45 seconds.
Pregnancy warning: LI4 is contraindicated during pregnancy.
TE5 / Waiguan — Outer Pass
Location: On the back of the wrist, two finger-widths above the wrist crease, between the radius and ulna.
What it does: The luo-connecting point of the Triple Energizer meridian, which also runs through the forearm and elbow region. TE5 is included in many tennis elbow acupuncture protocols specifically because the TE meridian covers the posterior forearm where much of the pain originates. Also effective for wrist pain that co-occurs with lateral epicondylitis. 45 seconds.
Ahshi Points — Tender Local Points
What they are: "Ahshi" means "that's it!" in Chinese — these are tender spots that aren't named points but are directly over the pain source. For tennis elbow, press along the outer forearm and find the most tender spot. That's your ahshi point.
What they do: Directly releasing myofascial trigger points at the site of tendon tension. The combination of ahshi + LI11 + LI10 creates a local-and-distal protocol that mirrors what acupuncturists use clinically.
A Practical Protocol
Daily maintenance (10 minutes):
- LI11 — 90 seconds. Start here every time. It will be tender; that's appropriate.
- LI10 — 60 seconds.
- Ahshi point — 60 seconds on whichever spot is most tender along the forearm.
- TE5 — 45 seconds.
- LI4 — 45 seconds to close.
Apply on the affected arm. If you have bilateral symptoms, do both sides — the unaffected side first to establish the routine, then the affected side where the tenderness will be significant.
Ice + acupressure: After the acupressure session, apply ice for 10–15 minutes. The combination of pressure work and cold therapy appears more effective than either alone for tendinopathy pain. Use a bag of frozen peas wrapped in a cloth rather than ice directly on skin.
During activity: If you're working at a keyboard or doing manual work, a brief 2-minute LI11 pressure session before and after the activity can reduce the post-activity pain spike.
What to Expect
Tendinopathies heal slowly. Four to 12 weeks is a realistic timeframe for meaningful improvement with consistent treatment. In the first week of acupressure, you may notice temporary soreness at the pressure points — that's normal and indicates the tissue is responding. If the soreness persists more than 24 hours or worsens, reduce pressure intensity.
The evidence suggests acupressure/acupuncture is most effective in the subacute phase (2 weeks to 3 months after onset) rather than in chronic cases lasting over a year. Chronic tennis elbow may need physiotherapy-guided eccentric loading exercises alongside acupressure to address the tendon structure directly.
When to See a Physiotherapist
Acupressure is a good bridge while waiting for physiotherapy — it reduces pain and may slow deterioration. But physiotherapy-guided eccentric exercises (Tyler twist with Thera-Band, wrist extensors program) have the strongest long-term evidence for tennis elbow. Physiotherapy for this condition is covered by most Canadian extended health plans (typically $50–120/session, $500–1,000/year coverage).
See a doctor rather than physiotherapist if: the pain is severe and acute after an injury, there's swelling or visible deformity, you have night pain that wakes you, or symptoms don't improve after 6–8 weeks of conservative treatment. Persistent cases may warrant imaging to rule out radial tunnel syndrome or partial tendon tears that require different management.
For the wrist pain that sometimes accompanies or follows tennis elbow, see the carpal tunnel guide. For general upper limb overuse pain and the WFH context, the upper back guide covers the posture chain that often contributes to forearm tendinopathy.
This guide is for informational purposes only. Lateral epicondylitis with severe acute pain, significant functional limitation, or failure to improve after 6 weeks should be assessed by a healthcare provider. Acupressure is a complementary approach, not a substitute for physiotherapy or medical management.
