Hi, my arm has been bother me lately after lifting anything 40lbs or more and when raking in my yard. I would think it would be tennis elbow, but its my bicep and the top part of my forearm. When I looked up tennis elbow they said it was the lower part of the elbow by the forearm. The pain will go away after I lift something heavy, like an hour. I am in decent shape, I'm 38, M, 245, workout, run, 3 times a week. I do need to get down to 230. But never had this pain before.
