Some advice please. Just visited docs, slightly low level vitD, 6.5. I'm on 50 mcg levothyroxine. Doc says that my thyroid tests normal, I questioned him on tsh being 4.55, saying that people feel better, when it's in the lower level. He said that, that is the levels they go by. He said what do u want me to do, obviously he has to go by them. So I asked him if I could up my levo to 75mcg. As a trial to see if I feel better. He said I can manage my own meds, that its down to me. Am I doing the right thing, I feel if I don't try the extra 25mcg. I'm not going to feel better, will be having bloods done in 8 weeks.
