I think I may have a stress fracture in my arm. Although I don't remember getting armbarred very bad recently my upper arm always has a really bad dull ache after rolling. Last couple of days it's so bad that when I'm driving home I find that I'm driving with one arm and the other is just laying in my lap.....with the upper arm throbbing. It's not the muscle that aches, and it's in the middle of the upper arm so it's not the tendons/ligaments either. Anyone ever have this? Guess I'm just going to go easy for two weeks maybe and up my calcium intake.
