Thank for asking to HCM
I really appreciate your concern the fibromyalgia
is it self a psychological disease, such disease may manifest in other way also like you have stated here, the hypothyroidism
does not induces any symptoms like that, and nothing to worry about that, for your symptoms it would be better to keep the stress
level very low, every thing would be fine, vitamin supplement some times gives good result and that is worth trying, take care and have nice day.
