I think tam had bad sx on the underside of her forearms at the beginning of her injury , mine was worse on the topside with sharp cramps in the back of my hands . forearms had a constant tightness, pulling, weird buzzing feelings {at the beginning of my RSI} and hypersensitive for awhile after the ulnar nerve flared.

after I saw some of the anatomy sites i found a lesser mentioned nerve that feeds the areas - musculocutaneous nerve
