I was diagnosed with Hypothyroidism in 1999 TSH 5.17. Since then I have been on Thyroxine, started at 50mcg and had gradually over the years gone up to 125mcg (which has now been put back down again to 100mcg). My blood test reading in June was 0.04 TSH so classified as Hyperthyroidism, so was told to reduce dose to 100mcg. Just had another blood test result now 0.4 TSH so I now have to remain on 100mcg, as doctor says that is the correct dose for me.
The problem is since reducing the dose from 125mcg to 100mcg in the last two months I have started gradually to feel absolutely terrible - I can now barely function. Fuzzy head with headaches, slow thinking, forgetful, generally slow, exhausted, tired, sleeping badly, no spark, low mood. My right leg keeps giving way. All the symptoms that I have had in the past when my thyroid was low.
Have been back to GP he says the problem can not be with my thyroid and says the HRT (which I have been taking for the past two years) would not have any affect on my thyroid the opposite in fact! So I am going to have a full fasting blood test as he believes the problem lies elsewhere. I don't really understand this as I have only been feeling like this in the last month. When my dose was higher I did not have all these symptoms.
