What this muscle is
From the back of the ulna, around the back of the wrist, to the last bone of the thumb. It straightens the thumb.
Why it gets uncomfortable
Straightening the tip of the thumb to tap a screen; repeated rubbing on the back of the wrist.
How it usually feels
A sore tendon from the back of the wrist to the thumb; the tendon jumps when you straighten the tip; sometimes it sticks halfway.
What helps
Bend the thumb into the palm, make a fist, and gently bend the wrist. Hold 20 seconds. If the tendon suddenly will not glide, see a doctor.
