What tests should dr be checking when doing follow up blood tests? I got a phone call from dr 2 weeks ago telling me that I am now on correct level of thyroxine (100)mg a day. When I said I was surprised as I don't feel any better he told me that due to being ill for the last year (I had ITP now in remission) that it will be about 6 months before I feel better. Just doesn't seem right to me. I'm going to see him tomorrow and would really appreciate any help with what I should be saying to him. I just don't feel I can put up with this for another 6 months to then possibly find I still feel the same.
