My T3 and T4 levels are mid range but my TSH level has rocketed to 50. My endocrinologist has recommended upping my dosage to 75, but this is making me feel very unwell - dizzy, bad headache, tingling in my fingers, heart pain. I would like to go back to 50 mcg or preferably even lower, but I'm worried what the long term effects of this will be with such elevated TSH levels. I have reviewed all the literature and can not find any advice that meets my circumstances.
