Today, I was sitting on the couch when a pain in my shoulder occurred (left side). I've had this pain before, so i brushed it off as i assumed it was growing pains (Im 16, female). Later on, both shoulders erupted in pain. I tried massaging, ice packs, heating pads, laying down, but every time i lied down the pain would act up again. The left side doesnt seem as bad as the right, yet it has spread up to my neck and collar bone when i lay down. My right shoulder seems more stiff and painful to the touch. Please help
