Hi there I have been on levothyroxine for approx 8 years. I am on 100mg..last year my TSH was low and my doc then dropped my dose to 75mg. I hit the deck running and felt horrific and put it back up to 100mg. Same thing has happened my THS is low 0.045 2nd test has changed a b it 0.142. I am having probs with the doctor doing a T3/T4 blood test he keeps saying he has to ask the hospital for them to okay it. Meanwhile I show no signs of overactive thyroid and my weight is going up help? Should I go and see an endo privately?
