I'm actually writing on behalf of my sister who's hospitalized right now. She has been experiencing severe shoulder, arm and hand pain, inflamation and tingling sensation for some years now and has been receiving physical therapy. Last week, however, she fainted twice and was hospitalized. She's having now problems moving her right leg and loss of balance. The doctors seem to be at a complete loss and think she might be diabetic, but her blood tests were normal. Her blood pressure is also a little bit higher than usual. She was tested 2 years ago for rheumatiod arthritis, lupus and MS and everything was negative.
Any ideas? Could this be a combination of illnesses like cardiovascular and some kind of arthritis, or could it be some sort of neurological disorder?
Thanks for your help.
