Hi I am new to this site and have had an overactive thyroid for over two years (I have had this happen three times in the past but it has cleared up after Carbimazole treatment). This time was different in that I felt so ill with it, terrible shakes, aching eyes, and very painful muscles at the front of my lower legs. I have now been on Carbimazole for over two years, but I am still sweating really badly if I undertake any form of exertion, and yet my blood tests are fine. I dance (jive dancing) and find that during dancing, I really overheat and after dancing it takes me at least 2 hours to stop sweating - its so embarrassing. I am post menopausal, and do have hot sweats and night sweats, but this is something else. If I become anxious I tend to overheat as well - I am being treated for anxiety due to my hyperthyroidism. Does anyone have the same problem, or know how to control this?
