hello,i had surgery on my right forearm 1 and a half month ago (cut radial nerve,extensor tendon and radial vein) 6 days ago i removed my cast,but 2 days ago i slipped and fell and felt great pain around my wrist which lasted for 1 hour and ok.. but today,when i touch or lean my forearm on something,i get al electrifying weakness pain which sprads through my whole arm (i feel it best a few mm left of my medial nerve). maybe its a ulnar nerve.my pinky and ring finger twitch a little randomly.is it serious? my whole left side of the right arm feels weak and this electrifying feeling which lasts for a couple of hours
