i was diagnosed with an underactive thyroid a while ago and am currently on 100 mcg of levothyroxine this was reduced slowly from 125 mcg, recently i have been feeling unwell and have been diagnosed with plantar fasciitis which i understand is related to my thyroid. my doctor seems unaware of the link and at my most recent blood test in august my tsh levels were 0.38, although i tell my doctor i do not feel right she will not do another blood test for another month at which point she will check my t3 and t4.
what i need to know what are and are there any other test i should be requesting?
Also is there any literature I can get hold of to give to my doctor explaing that a normal tsh doesn't mean a healthy patient?
