I have now been on Levothyroxine 50 mg for two weeks (yep I know early days) and feel absolutely awful. Not too bad in the morning but the afternoon my lower legs hurt and I am really tired. Getting lots of pins and needles. Very sore throat and headaches constantly. Bloods due in six weeks. Doesn't help that I work shifts. Not sure what the underlying cause is for getting hypothyroidism in my case but doctor does not seem interested in finding out as TSH was not that high (6.5) so just told to take pills and report back in eight weeks for more bloods. Guess what I want to know is 'is this normal' or should I go back earlier?
