I came on a few months back--here's the brief history. I'm 41, have had Hashimotos' hypothyroid for 15 yrs, on med for that. In January, I changed birth control from one I'd been on 12 yrs to one with lower estrogen (in case that's relevant--it was my only change--no accidents, injuries, etc)
So in January--the pain started as carpal tunnel, but got severe and progressed to my arm and shoulder. Labs in March showed normal sed rate, neg ANA, neg RH factor. B12 was high (>1000), folate high at 17. Only abnormal was my TSH had gotten way high (9.75), we increased meds, it began to fall--normal limits now.
A Physiatrist suspected TOS, did an EMG done--showed CT. I started PT and after 7 weeks, no improvement, pain had spread all over chest area. The pain is a burning--lit on fire, not tightness.
Saw a neurologist--a good one rec by someone on this board--he did a lot of manual tests, and said a type of paresthesia--perhaps caused by my thyroid, and to wait until that was normal--it has been tech. normal 2 months
Currently the pain moves--wrist, shoulder, chest, breasts, stomach, arms legs.
I have not tried any prescr. meds. I am hesitant because I take 2 thyroid meds, and metformin and birth control (for pcos).
Side note--I am thin, 102lbs. (With my conditions this is not the norm, so I thought I should add).
Things that somewhat help--ice pack, or a hot bath--both temp. relief. Moving, walking helps. But now the pain is so bad at night I cannot sleep.
Sorry for the length/if this is the wrong place. Thanks for any help/advice.
