Hello. I m 41, and two years ago while doing pullups, I felt something give in my left biceps. As a former athlete I am familiar with broken bones, sprains, tendonitits, et cetera, but have been surprised that my biceps has ached off an on for two years. There is no bulge indicating a torn tendon, and really there has been no loss of strength either. Like I said, I m surprised the dull ache has continued and am asking for a course of action. Thanks.
