Shoulder pain My left shoulder has been paining since about 2 months, i visited the PT and he seems to think it is a muscle pain. I have been doing various exercises but of not much help. As the pain has been there for about 3 months, i am worried it may be due to bond damage due to myeloma. Wanted to check of bone related pain symptoms? Is it very painful? Consistent throughout the time it started? Any other description of the bone damage related pain would help me.
