Elbow pain

I have had elbow pain for about a month and a half now. Tried throwing the other day and elbow hasn’t improved. I think I hyperextended my elbow originally. Now every time I throw, at release, I feel like my elbow is extending to far. It seems like its more in my forearm than my elbow. Can anyone explain what might be wrong? Any help would be appreciated. Trainer says its tendenitis and a possible pinched nerve.

You should go get checked out by and orthopedist or sports doctor. Your pain could be caused by a number of things some of which would require you to shut down to let them heal properly.
