Have had almost constant upper back pain (just underneath shoulder blades) for 4-5 months now. Went to the doctor a few weeks ago who examined me thoroughly and sent me for an x-ray wihich turned up nothing. I had thought it was from lifting DD who's 3 but have made a conscious effort not to and the pain's still there. It's so bad it wakes me up at night and the only thing that stops it is ibuprofen. Am at a loss as to what it can be (discounted any injury, bra being too tight or it being muscular etc) and am wondering whether it could be related to my stomach. Has anyone had anything similar or able to advise?
