I am 21 years old, high level player, and I started to develop GE. I finally told myself I would stop playing for a bit. It has been a week, and I know that is nothing, and I am going to start physiotherapy this week, but what confuses me is that I have NOT played and my elbow hurts me sometimes at night and when I wake up. I get pain when I try to straighten out my elbow and it gets really tight and stiff. Why does this happen if I am not even playing???
