Outer forearm · Uncommon
What this muscle is
From the outer bump of the humerus at the elbow to the little finger. It straightens the little finger.
Why it gets uncomfortable
The little finger stays lifted while you type; a backhand; repeated bending of the wrist backward.
How it usually feels
A thin cord on the outer forearm, near the elbow, feels sore; straightening the little finger tugs the outer back of the hand.
What helps
Bend the elbow. With the other hand, gently bend the little finger toward the palm. Hold 20 seconds. Do not bend the wrist back until it goes numb.
