What is brachioradial pruritus?

The brachioradialis is the muscle in the lower part of the arm that helps the arm bend at the elbow. Brachioradial pruritus is a nerve disorder that causes itching, stinging, or tingling sensations in this area of the outer forearm.

Brachioradial pruritus usually affects both arms, but it can occur in only one arm. In rare cases, the urge to scratch spreads to other parts of the body, including the shoulders, neck, and lower legs. This condition is not contagious.
