The first real symptom was plantar fasciitis. And poor sleep.There is the possibility of bone marrow suppression (fortunately rare). How did your hypothyroidism begin? In my reality these things are invariably systemic (regardless of medical research - I knew it was the stress of a newly qualified job and 16 espresso and 50 ciggies a day that triggered the graves)
This occurred after giving up smoking and having a lot of high stress things happen.
My TSH was tested, several times, and each time it had risen. FT4 below bottom of reference interval.
Started levothyroxine and things pretty much got back to my normal.
