Definitely check on the antibody levels. I felt unwell for years,
complaining to my PCP that I was tired, depressed, dry skin, irritable...my TSH (which it the only thing they tested at that time) was within range 1.4 - 2.8 every time. No test for antibodies was done.
Meanwhile, the antibodies were attacking my thryoid over the years wreaking havoc and causing the development of nodules (my assessment)
Recently I requested all of my labs back to 1999.
