Diagnosed Graves Disease in 1992. Had RAI in 1997. Hypo since then. But after 2 major surgeries now am hyperthyroid again. Primary care dr increased my levothyroxine from 175mcg to 200mcg and I feel worse than ever. Isn't my medication supposed to be lower? So confused. And losing weight, irritable, not eating, not sleeping, very hyper. Help!!
