Hello! I have Multiple Sclerosis and I have been having some issues of not feeling myself. I feel lightheaded at times, my head doesn t feel right, I have been having problems with my blood pressure being high with uncontrollable shaking like if I m nervous. Sometimes I feel nauseous, right arm pain, loss of balance, heart palpitations. Nobody seems to know what s wrong. Been hospitalized twice in the past month and a half. Had an EKG, stress test, brain MRI and an ultrasound of my chest and all came back negative. I am taking Gilenya for my MS and now my family doctor put me on Metoprolol for my blood pressure and I just found out those two medications taken together has a drug interaction. But my symptoms that I have been having all started before I was on the blood pressure medication. Can you please help? My email is YYYY@YYYY . Thanks, Tammie
