Elbow pain/tendonituos

I was told I had elbow tendonitous lats year and I went to PT for it and everything like that. But when I began to throw again the pain came back. It’s not as bad as it used to be but the thing is it doesn’t hurt in the throwing motion my pain comes after I throw. After I throw a few balls and move my arm around my elbow hurts on the outter part. I don’t know whats wrong any help?

Could I have this problem because I turn my wrist kinda to the right when I throw(turn so my palm faces upward)?

That’s certainly a possibility.
