My wife, 66/3, suffers from back pain. It is located between her shoulder blades. Seems to come on whenever she starts to do anything at the counter top eg. cooking, washing dishes, ironing. She can't take any of the aspirin type painkillers, because they are too hard on her stomach. Any of the Tylenol types don't help. Our neurologist says he doesn't think it has anything to do with PD. We are beginning to think otherwise. Any similar symptoms out there?
