I get tested every year for thyroid function and have a lot of the symptoms but the test always comes out as 'normal levels'. I have lost pretty much all of my pubic and underarm hair and what's left has turned white. I suffer from cyclical PMT which can be worse if I have had a hectic month. My mother has hypothyroidism and is on levothyroxine. I am gaining a kilo of weight every month and feel the cold easily.
