Location & How to Find

How to Locate:

  1. Look at the back (dorsal) side of your thumb
  2. Find the joint crease in the middle of your thumb
  3. Locate the center point of this crease on the back of the thumb
  4. This center point of the thumb crease is EXT-29

How to Apply Pressure

Once you have located EXT-29 at the centre of the thumb's middle joint crease, press gently with a fingertip and never lever or bend the joint against the pressure. Avoid it after a thumb injury, over infected skin, or on arthritic joints that hurt more with pressing.
