I have pain in my shoulder, upper bicep area that will not go away. It is often very sharp pain. I have not been injured that I know of. I thought that maybe I slept on it wrong or something, but it s been about a month and won t go away. I ve used a tens unit, and that seems to help, but only temporary. What could this be? What type of specialists would be best to go to for help? I m 43, male, 5 11 , 230lbs and fairly active. Prior to a separate injury in my leg last year, I ran 5-6 times a week for 4-5 miles. Since that injury I have gained about 20lbs.
