Although I live in US I have read many posts here re this problem. I have been bothered my this for too many years and dr cant seem to help. Sometimes I get pain in calf of leg that I cant walk. I swear it has something to do with the lymph nodes and or the thyroid meds now on 150 mg of tirosint. I thought it was wrong to take iodine-any help I can get would be appreciated, primary dr doesnt know what to do.
