I was diagnosed with graves disease 8yrs ago and had my thyroid gland removed. I have been on 250mcg levothyroxine since then. I have been suffering from a kind of muscle weakness, aching all over. I don't know what my tsh reading is because I got so fed up with the so called specialist at the hospital telling me I was fine and there is nothing wrong with me that I gave up going. I resigned to the fact that I would always feel like this and just have a blood test at the GP,s request when needed. As a postman I have struggled doing a job I love. (I work in vector iow. Very hilly). I have learnt through this wonderful site that I could need t3. I have purchased some and wondering how much to take? Took my first today. 150mcg levothyroxine and 25 tiromel, as it's 4 times stronger. Any e,pert advice would be much appreciated.
