Hello all - has anybody else experienced burning calf muscles and feet. It comes and goes - sometimes cold but normally very hot. I've got hashi and take 125mcg of thyroxine. Im still not under 1 tsh (results next week but was at 4.3 in July) but have regular spasms (very painful) along these muscles and tingling in my extremities including my toes, fingers, hands, feet, head - it makes me feel very unwell, jittery and tearful. Has anybody else experienced similar symptoms and been able to overcome? Do these symptoms usually go once tsh has reached an optimal level?
