i hyperextended my elbow about 4 weeks ago playing football. I only have pain in it when I have quick sudden movement with my arm. I can lift things with my arm and pretty much do any other thing, but when I hit something with the bad elbow I occur pain, then it doesn’t bother me. example when I play volleyball I can’t hit the ball with left arm because the pressure of the ball hitting my arm causes discomfort. just wanted an opionion on what I should do. thanks!
