Methimazole and medicine

I was started on Methimazole for Graves, 10 Mg daily. Three weeks after I started taking it, I broke out in hives all over my body - not little itchy spots, huge welts that had red edges and yellow centers. My endocrinologist said it was likely an allergic reaction and I should stop taking it.

I did stop, but four weeks later, I am still not well. I have mild itches and am weak, I have trouble sleeping and concentrating. I cannot walk for more than a few minutes without sitting down. The interesting part is that proprinal has a 50% chance of the same reaction.

We are back to monitoring labs and going nothing. I have never been so sick in my life, and I am now going to try non-traditional medicine to see if I can address the thyroid issues that way.
