I was recently diagnosed with hypothyroidism and showed high RT3 levels. My doc put me on 10mcg of cytomel. Anyway, I don't know if that has anything to do with my present condition or not. I have vitiligo on my shoulder, back and neck and also my left knee. It doesn't seem to be subsiding and is starting to spread. I think my vitiligo has always been an underlying condition but was triggered by the finacea that one of the dermatologists prescribed for my papulopustular rosacea.
