my mom is 76 years old and very active. about 4 months ago she started having upper muscle pain in her arms like she worked out which she didn't. i took her to ther doctors and they did an mri and it showed nothing. they gave her a cotizone shot which did nothing. she cannot sleep and cannot put stockings on without alot of pain. she takes moltrin and tylonel muscle tablets but nothing helps. nobody seems to know what it is but it is driving her crazy. does anyone know what can help or who she should go see. she knows of three other people who have this-one is going to physical therapy but its not helping. thank you
