I am having muscle cramps from hell in the area of my ribs on the right side and it seems to wrap around all the way to the center of my chest (at the bottom of the sternum). I also have some pain and muscle cramps in the center of my upper back, but I don't know the level number. I don't know how many MRIs I've had and the doctors haven't found anything to explain my symptoms, which is extremely frustrating. I also occasionally have a weird muscle spasm deep in my chest. It almost feels like my heart, but I don't think it could be that. Anyone else here have a thoracic spine condition with symptoms like I've described? Thanks.
