Along time ago I strained the bottom of my tricep while doing chin ups and today the pain returned while I was doing pull ups. The part that hurts is at the bottom of my right tricep near the elbow and only hurts while pulling myself up and my eyes are near the level of the bar. It is a sharp pain that happens and goes very quickly and I have also felt it while flexing my bicep.
I don't believe this is tennis elbow, from what I know tennis elbow is on the forearm? Could it be improper form? Are there any stretches or anything like that I could do to help?
