I've not been diagnosed but I have to be retested for underachive thyroid- I've been reading people's threads and is it wrong be be hoping that all my symptoms will be expelled by the Dr conforming that I actually do have an underactive thyroid!! I'm feeling really down with feeling like a "fat knacker "!!!! I get really sweaty late at night- although I've been shivering all day, I feel myself expanding after every meal, just all the symptoms match- I don't know what I'll do if the test results come back negative. A positive test would make sense of it all!!!
