I've recently been experiencing sharp pains in my right arm when I turn it or flex it in certain ways. The pain seems to be concentrated on the underside of my biceps (triceps?). There are no other problems in addition to this. Also, I'm not sure how it started, except that I first felt the pain during sleep and woke up because of it.
Does anyone know what could be the cause and how to alleviate the pain?
