After I come inside from tossing around a football, I get this pain in my elbow. I only throw for about 15-20 minutes at the most. For 3-5 hours after I stop throwing my elbow on my throwing arm hurts really badly. It causes my hand to shake. The pain intensifies if I move the joint. The pain is kind of like a throbbing, but it hurts more than if something throbs. I don't think it is from throwing too much, because the pain just started about a week ago. Any advice is appreciated.
