I just answered the questions about itching with no rash and thyroid disorder was suggested. I have hashimotos autoimmune thyroid disease and take synthroid and my ths results are around 1.0. I have itching on my scalp and other personal area where there is hair. I don t scratch because you can t do that in public but it feels so irritating. I have considered my other meds - Allegra, topamax, provigil, and Lipitor as the cause as well as heat or some type of mild fungal rash that just does not show up on my pale skin. How could it be connected to thyroid? I ve tried creams, hydrogen peroxide, even baby ointment. Any suggestions?
