I was recently diagnosed with Graves Disease, very high t4, t3 and very low tsh, high antibodies, uptake and scan 90.2%. I am currently on beta blockers and methimazole for 1 month. My heart symptoms, high blood pressure and pulse of 120-160 are now close to normal but I still have other symptoms, hot all the time, extreme sweating, insomnia and worst of all very intense muscle pain especially in my thighs but in the rest of legs and arms too. It seems to me that this muscle pain is getting worse every day, so bad to the point that I am in tears. I can't walk up stairs without holding railing, can't stand up from a squatting position, if I stand for very long my legs start uncontrollably shaking, I have to put the car in park when stopped at red lights because I can't keep the brake down from pain and leg shaking. Sorry this is such a long post but my question is has anyone else experienced this and what helped? My endo just keeps saying it will get better.
