d like to know if untreated long term (30 years) subclinical hyperthyroidism (MNG) can cause thyrotoxic
myopathy. The doctor I saw 5 years ago said that I was just mildly hyper
and that it couldn't cause my symptoms, which included climbing up the stairs on my hands and knees, difficulty rising from a chair, painful quads, stiffness, loss of shoulder-girdle and pelvic-girdle muscles and muscle cramping. The specialists I've seen haven't been able to find any other cause.
