I don't know what I did or how, but I somehow managed to tweak my left forearm at the top insert point into the elbow ie) either the brachioradialis or biceps brachii.
It may have been from doing power cleans.
I have been trying to slowly work it out.
I can do chins (pronated and supinated grip) but it burns like hell.
I can do light curls (supinated) and hammer (they burn like hell) but cannot do reverse grip curls.
Anyone ever experience this and how did you work it out??
