I finally managed to talk to a GP about getting a referral to see an endocrinologist regarding my Thyroxine medication. No referral has been forthcoming, but my levo has been raised from 100mcg/125mcg alternate days, to 150mcg daily. Blood test in six weeks. Apparently my tsh last blood test showed I could need a slight raise (but I wasn't told this), however "we don't want the tsh to go too low or I'm in danger of osteoperosis and brittle bone disease"
Symptoms persisting include lack of energy, joint pain, air hunger. Probably more I don't know of. Apparently the Endo will not be able to do anything for me as I have no gland, even if I was referred.
