Hello I just thought I would introduce myself. I am 44 years old and have had thyroid probs for around 3 or 4 years now which they still don't appear to be able to control. I, like everyone else started small on the 25 a day but after every blood test, it appears to be worse so I am now on 300 a day which is high I know. I have just started on the 300 and am currently awaiting a referral appointment to see an Endo. I have a ultrasound on Tuesday afternoon too on the thyroid to see whats going on there but am unaware of what happens there. I have been looking through the threads on here and see the problems that people are experiencing and it is comforting to see that others also have the same problems and I am not alone.. my levels over the last 3 months have been 1.7 in March, then 47.9 in June and August it was down to 12.7 so as you can see up and down.
