I've been hypothyroid for 4 years. Up and down at times and my Levo I was prescribed has been adjusted a few times (up and down). I've recently felt awful, notably foggy headed, unable to concentrate, achy, basically what I felt pre-diagnosis. I got a blood test which was normal! GP won't do anything for me even though I feel terrible. Won't refer me as my levels are normal! What can I do apart from go private? I've already asked for all my blood test results from the past 4 years. I'm based in East Sussex.
