I have had a set of very debilitating symptoms for some time now that I should really have gone further with the doctors with but felt like it was just CFS at the time. I finally found out from my parents today that we have a long history of hyperthyroidism and that might explain a lot.
Worst symptoms are fatigue (14 hours~ sleep per day that is completely unrefreshing), difficulty processing what people are saying to me (I hear it but it just doesn't process, as if they are speaking another language. It's difficult to describe), poor memory and concentration, brain fog, various problems with my vision, tremor, long history of mood problems that have never really been given a straight diagnosis, insanely fast metabolism despite being a skinny kid (2500+ calories to maintain weight).
First popped up about 4 years ago, and I went to the doctor who referred me for bloodwork. To our surprise it all came back clean. Was offered a retest (as they suspected thyroid problems at the time) and failing that an MRI, but I didn't go back as I had exams (and in hindsight I have absolutely no idea why I didn't go after that).
Very recently my hair has started falling out and my sense of smell has gone AWOL. So I had more bloodwork today and will get results next week.
Tl;dr, I just want to know if anyone has been in a similar situation, particularly hear from anyone else with a thyroid problem. Anybody ever had false negatives on a blood test? I was told by my GP back home that the test isn't the most accurate hence being offered a retest, but my GP here told me it is very accurate. And if it's not a thyroid problem I have really no idea what to try next.
