Re: How rare is viral thyroiditis? What virus could cause this
Subacute viral thyroiditis is pretty easy to diagnose. you would have very high hormone levels, inflammation of the neck, sometimes a fever, and a low tsh, and if you take an uptake scan, despite being hyperthyroid, you would have a low uptake. It doesn't have anything to do with lyme disease, it's some sort of virus that attacks the thyroid, it's really uncommon, and usually cycles out in about 3-6 months. A doctor would find it without too much difficulty.
You could have a thyroid disease, not virus based, and that could be tested for as well, but again, I don't think it affects lyme disease numbers, it's a autoimmune disease
