So my TSH level is only 4.2 and here the reference range is 4.8, but i'm experiencing almost all the symptoms and I can barely manage my life like this. Last year my TSH was 2.5 so it's obviously increasing. My GP said that it's still in normal range so she won't start the treatment. My question is , what should I do? Should I wait until it get's worse? or should I search for another place where the ref. range is lower? Or is it the lowest it can get? Thanks for the answers and sorry if my english is bad!
