Sharp Forearm Pain Doing Curls

sharp forearm pain doing EZ curls/straight bar

i had this in high school also but that was ~ 2002 and now its back again. i’ve recently went up quite a bit in lots of lifts including bicep movements and wondering why the sharp pain is back that follows the bone on the pinky side of my arm, i believe the Ulna?



is it when you release your grip?
