When i'm doing curl or bicep exercise (more when my palm face the ceiling) I feel pain in my forearm between my wrist and my elbow. The pain is situated on the side of the ulna.
The pain seems to come when I release my grip.
Did someone know from where it's coming; muscles, nerves, ... ?
EDIT : I've check with a professional and it seems to be my muscle the "Extensor carpi ulnaris"
Did someone know if it come from a bad form or too much weight ?
