I have Grave s disease. I was diagnosed when I was 19. I took PTU 300 mg for 3 years and 100 mg for 2 years. Ever since I was 22 I have had hypo symptoms. I have prolactation of my breasts, frequent throat infections. I had my tonsils out when I was 24. I have been treated with psychiatric drugs for my symptoms. I have been very sick sine I was about 30. My health has been declining. Im on BP meds and they wanted to put me on Cholesterol meds. Now a new doctor looked at my TSH reading only and saw it was 5.8 and said it was slightly high . I went from .008 with full blown graves and a goiter and now it is at 5.8 and I feel like I should be 6 feet under. My question is should I be on a higher dose than 50 MCG and will the levothyroxine cause the Graves to come back. I am confused. I feel let down by the medical community. I have suffered for over 15 years with this debilitating disease. Please help. No one will help.
