I have Hashimotos, and my last blood test result for TSH was .020 which was way too low, so GP suggested that I reduced my thyroxine from 125mcgs to 100mcgs. I was unhappy doing this, as I was concerned that symptoms would return - severe fatigue, aching muscles and joints - so we compromised and I agreed to take 100 and 125 on alternate days. Within a week I felt like hell, all symptoms had returned, as I had predicted, so I discontinued the 100mcgs, and just continued with 125mcg daily again. And I continued to feel 100% well. When I needed a repeat prescription in Dec, I did write letter for GP, explaining the situation. Today I had TSH tested at work, results = Undetectable. T4 too high at 25.4 too. I know my GP is going to tell me to reduce thyroxine again, and same thing will happen again. Endo I saw in Oct just said reduction in thyroxine and symptoms returning were just coincidence, and discharged me on first and only appointment!!!!! Any suggestions anyone, as I am getting perilously close to the end of my tether.Thanks.
