Just wondering if anyone else with Grave’s Disease has also developed Polymyalgia Rheumatica (PMR)? My third autoimmune disease just got diagnosed this month. The only treatment is steroids, which have numerous side effects, one of which is they seem to lower my FT3 pretty dramatically. I take Armour Thyroid plus a small dose of supplemental Synthroid. On Prednisone, my FT4 is at the high end of the normal range while my normally middle of the range or higher FT3 has plummeted. This is happening on the same dose of replacement that I have always taken. Anyone knowledgeable about the effects of steroids on FT3? And if so, what to do about it?
Thanks!
