Carpal tunnel syndrome and non-specific wrist pain are among the most common repetitive strain injuries in Canada. The shift to remote work during and after 2020 created a surge of improvised home workstations — kitchen tables, laptop stands, mice perched at the wrong height — that dramatically increased wrist overuse injuries. Canadian physiotherapy clinics and orthopedic waitlists haven't fully caught up with the demand.

Acupressure at the wrist and forearm doesn't replace ergonomic correction or medical evaluation, but it is genuinely useful for managing day-to-day symptoms between treatments. The four points covered here — PC6 (P6), PC7, TW5, and LI4 — address different aspects of wrist and hand pain: nerve compression, tendon tension, extensor overload, and systemic inflammation. Used together, they cover the full picture.

Note: this page focuses on the point mechanics and technique in depth. For a broader discussion of carpal tunnel syndrome in the Canadian healthcare context — surgical waitlists, ergonomics, conservative care pathway — see the Carpal Tunnel Canada guide.

Understanding the Four Key Points

PC6 / P6 / Neiguan — Inner Gate

Location: On the inner (palmar) surface of the forearm, three finger-widths (using the patient's own fingers) up from the centre of the inner wrist crease, between the flexor carpi radialis and palmaris longus tendons — the two prominent cords that become visible when you make a fist or flex the wrist slightly. If you can't see the palmaris longus tendon (about 14% of people lack it), the point is between the flexor carpi radialis tendon and the midline of the forearm.

What it does: PC6 is arguably the best-studied acupressure point in existence, primarily for nausea — but its wrist and hand applications are equally significant. It lies on the Pericardium meridian, which follows the path of the median nerve through the forearm. Stimulating PC6 reduces tension in the flexor tendons, which are the main contributors to carpal tunnel compression (the tendons share the tunnel with the median nerve, and their inflammation takes up space). It also improves circulation to the distal hand.

Technique: Use your opposite thumb, placed perpendicular to the forearm. Apply steady, moderate pressure — firm enough to feel a dull aching sensation (called "de qi" in TCM), but not sharp or stabbing. Hold for 60–90 seconds without rubbing. Repeat on the other side. Do not apply friction; sustained pressure is more effective than massage for this point.

Common mistake: Pressing too close to the wrist crease. Measure three full finger-widths up. The point is higher than most people expect.

PC7 / Daling — Great Mound

Location: On the inner wrist crease itself, at the midpoint between the two tendons (flexor carpi radialis and palmaris longus). If you draw a straight line from the middle finger down the palm to the wrist crease, PC7 is where that line hits the crease.

What it does: PC7 sits directly over the carpal tunnel. The carpal tunnel is the channel through which the median nerve and nine flexor tendons pass from the forearm into the hand. Applying sustained pressure at PC7 — directly over this channel — has a local decompressive and anti-inflammatory effect. Unlike PC6, which works higher up the forearm, PC7 addresses the tunnel itself. For people with classic CTS symptoms (numbness and tingling in the thumb, index, and middle fingers, especially at night), PC7 is often the most immediately relieving point.

Technique: Locate the two tendons by flexing the wrist slightly. Place your thumb between them at the wrist crease level. Apply gentle-to-moderate pressure — PC7 is often significantly more tender than PC6 in people with active CTS, so start light. Gradually increase to the point where you feel a dull, spreading ache but no sharp pain. Hold 60–90 seconds. Release slowly. The tenderness usually diminishes with regular use over 1–2 weeks.

In combination: PC7 and PC6 are used together in virtually all clinical acupuncture protocols for CTS — they address the wrist at two different levels, and the combined effect is greater than either alone. Always apply both.

TW5 / TE5 / SJ5 / Waiguan — Outer Gate

Location: On the dorsal (outer, back-of-hand) surface of the forearm, three finger-widths up from the dorsal wrist crease, between the radius and ulna bones. It is directly opposite PC6 — if you put your thumb on PC6 and your index finger on the other side of the forearm, your index finger will be approximately at TW5.

What it does: TW5 (Triple Warmer 5, also written TE5 or SJ5) addresses the extensor surface of the forearm — the opposite side from PC6 and PC7. This matters because wrist pain in keyboard users isn't just a carpal tunnel (flexor side) problem. The extensor tendons, which lift the fingers off the keyboard with each keystroke, also become inflamed and tight from repetitive use. Tight extensors pull the wrist dorsally, which indirectly increases carpal tunnel pressure. TW5 reduces extensor tension, improves dorsal wrist circulation, and is also useful for wrist pain that extends to the back of the hand and fingers.

Technique: Use the thumb of the opposite hand on the dorsal forearm. Apply moderate pressure between the two forearm bones — you'll feel the bones on either side and the tissue between them. Hold 45–60 seconds per side. For people with tennis elbow or extensor tendinopathy alongside wrist pain, this point often produces notable tenderness, which is a sign you're in the right place. See also the tennis elbow guide for the upper arm points that complement TW5.

LI4 / Hegu — Joining Valley

Location: On the back of the hand, in the web between the thumb and index finger. Find the highest point of the fleshy mound when the thumb and index finger are pressed together — that's LI4. Alternatively, place the crease of your opposite thumb along the web margin, and where the tip of your thumb lands is approximately LI4.

What it does: LI4 is the most famous acupressure point, and its primary action is anti-inflammatory and analgesic — it's called the "great eliminator" for its broad pain-relieving effects throughout the upper body. For wrist and hand pain, LI4 addresses pain in the thumb, index finger, and radial wrist — the area supplied by the radial nerve and the lateral forearm. It's particularly useful when CTS symptoms extend into the thumb base (the thenar area), and for the generalised hand aching that comes with sustained grip work or prolonged typing.

Technique: Firm pressure with the opposite thumb, pressing into the web tissue toward the bone of the index finger. LI4 responds to firmer pressure than the wrist points — you want a strong, spreading ache that radiates toward the thumb and up the forearm. Hold 45–60 seconds. Release and repeat on the other hand. Most people find LI4 produces a distinctive, satisfying ache that transitions to relief within seconds of applying pressure.

Caution during pregnancy: LI4 is traditionally contraindicated during pregnancy — it can stimulate uterine contractions. If you are pregnant, skip this point or use it only after 38 weeks and under guidance. PC6, PC7, and TW5 are all safe in pregnancy. See the third trimester guide for pregnancy-specific protocols.

Daily Protocol: 10-Minute Wrist Routine

This sequence takes about 10 minutes and is most effective done once in the morning before sustained computer use, and optionally again in the evening. You don't need any equipment — just your thumbs.

Step 1 — Right hand first: PC7 (90 seconds) → PC6 (60 seconds) → TW5 (45 seconds) → LI4 (45 seconds). Switch to left hand and repeat.

Step 2 — Wrist circles: After completing both hands, do 10 slow wrist circles in each direction. This isn't acupressure, but it mobilizes the joints and improves synovial fluid distribution after the pressure sequence.

For nocturnal CTS symptoms (tingling that wakes you): Apply PC7 and PC6 on both sides before bed, then put on a wrist splint in a neutral position. The splint prevents the wrist from flexing during sleep, which is the main cause of nocturnal CTS — the acupressure reduces daytime inflammation, the splint manages the nighttime mechanics. This combination is more effective than either alone.

Desk-break version (2 minutes): If you can't do the full routine, apply LI4 on both hands for 45 seconds each. It takes 90 seconds total and provides meaningful immediate hand pain relief. Do this every 90 minutes during heavy keyboard work.

What to Expect

Most people notice some immediate relief in hand tingling and aching after the first session — particularly with PC7. Long-term improvement typically shows over 2–4 weeks of daily practice. If you have moderate-to-severe CTS (significant thenar weakness, constant rather than intermittent numbness, or symptoms that don't improve with position changes), acupressure is a supplement to, not a substitute for, medical evaluation.

Nerve conduction studies (EMG/NCS) are the definitive CTS diagnostic test. If your symptoms are progressing despite conservative measures — or if you notice weakness or atrophy in the thumb-side palm muscles — book an appointment with your GP for a referral. In most Canadian provinces, the pathway from GP referral to nerve conduction study to surgical assessment runs 6–18 months, so starting conservative management early makes practical sense.

Safety Notes

Do not apply acupressure directly over broken skin, open wounds, or areas of active infection.
If you have severe osteoporosis or bone fragility, use minimal pressure at bony landmarks.
Stop if any point produces sharp, electric, or shooting pain rather than the expected dull ache.
Pregnant? Skip LI4. All other points on this page are safe in pregnancy.
People on blood thinners may bruise more easily; use lighter pressure.

Medical disclaimer: Acupressure is a complementary tool for wrist pain and carpal tunnel symptom management. It does not replace diagnosis or medical care. Progressive weakness, wasting of the thenar muscles, or constant (non-intermittent) numbness are signs of significant nerve compression requiring medical evaluation. Cervical radiculopathy (pinched nerve in the neck) can produce identical symptoms to carpal tunnel syndrome and requires a different treatment approach — confirm your diagnosis before committing to a CTS management plan.
