I myself have posted before, and have seen others also post question pertaining to having Mononucleosis (caused by the Epstein-Barr Virus), either recently or in the past, and if it contributed or caused their
thyroid issues. And the more I read and research, there does appear to be a
connection.
I know that personally, I had some underlying symptoms of being hypothyroid leading up to me contracting mono last fall…but the vast majority of my symptoms began after the mono!
