Fell on back about a week ago on a hard floor. right shoulder blade has been hurting since. pain goes from back all the way to right breast. help?

Time to be seen: Since it has been a week and it sounds like the pain is getting worse, it is time to be seen. While it is most likely a sprain or strain, it could be a fracture, or a more serious injury. I am sure you have tried heat or cold, and perhaps massage and over the counter medications, so with continuing problems you need a better answer. Consider seeing a do.
