Acupressure for Headaches: LI4 Point and Safe Use

By TCMPath · Updated 23 October 2026 · Educational guide

LI4, also called Hegu, is a hand pressure point described in patient guidance for pain and headaches. Acupressure uses finger pressure rather than needles. It is an optional self-care technique, not a way to diagnose a headache or guarantee that it will stop.

Start with the safety information below. Recurrent, changing or severe headaches need appropriate medical assessment.

When should you seek medical help first?

Get emergency medical help for a sudden, extremely painful headache, or a headache with weakness, confusion, trouble speaking, loss of vision, a recent head injury, or high fever and a stiff neck. Do not delay help to try a pressure point. For regular headaches or symptoms that persist or worsen, arrange a medical review. These warning signs are based on NHS headache guidance; use the appropriate emergency service where you are.

Where is the LI4 headache pressure point?

Memorial Sloan Kettering Cancer Center's patient guide locates LI4 on the back of the hand, between the bases of the thumb and index finger. Bringing those fingers together makes a small muscle bulge; the point is at its high point. Relax the hand once you have found it. See MSK's illustrated LI4 guide.

Do not use this point during pregnancy. MSK also advises against pressing where the skin is broken, peeling, blistered, irritated or showing signs of infection.

How is gentle acupressure performed?

MSK describes using the opposite thumb to apply circular pressure at LI4 for two to three minutes, then working on the other hand. Pressure should not hurt. If it becomes painful, stop or release the pressure. Refer to the illustrated instructions above if you are unsure of the location.

This is a summary of patient education, not a personal recommendation that the technique is appropriate for every headache. If you have an injury, a medical condition affecting the hand or any uncertainty about suitability, ask your healthcare professional first. Do not press harder to chase an effect.

Will a pressure point stop a headache immediately?

There is no result we can promise for an individual. A patient instruction sheet is not evidence that a technique treats every headache type, and feeling better after pressing a point does not identify what caused the headache.

The useful question is whether a gentle technique is comfortable and appropriate alongside your existing care, not how many points you can press. Avoid assuming that combining more points or using greater force will work better.

NHS self-care advice also includes drinking water, avoiding skipped meals and taking breaks from prolonged eye strain. Keeping a headache diary can help you discuss possible patterns with a clinician. Read the headache self-care guidance.

If you keep a note, describe when the headache started, how long it lasted, what else you noticed and any medicines you used. Treat the note as something to discuss, not proof that a food, posture or TCM pattern caused the pain.

Common questions about headache pressure points

Are acupressure and acupuncture the same?

No. Acupressure uses external pressure; acupuncture uses needles and requires an appropriately qualified practitioner. Searching for “acupuncture points for headache” does not make a self-needling procedure safe. TCMPath does not provide acupuncture or other in-person procedures.

Is LI4 suitable for migraine or tension headache?

This guide cannot identify which type of headache you have or select a treatment for it. If headaches recur or affect your life, ask a clinician about assessment and management rather than relying on a pressure point alone.

Can I use the body constitution quiz to choose a point?

No. The free self-reflection quiz records everyday habits and feelings. It does not diagnose headaches or generate a treatment plan.

What does an online consultation cover?

The US$25 wellness consultation covers general routines and gentle self-care where appropriate. It is not a headache assessment, an emergency response or a substitute for your medical care.
