Hi

I have been diagnosed with underactive thyroid and am on thyroxine, but my leves are fine at the moment. I still go through long periods of a time where i feel really unwell. This consists of me being tired, the whole time no matter how much i sleep, not being able to think, concentrate, remember. Having joint aches and pains, mouth ulcers, itchy skin and a general feeling of being unwell. I have been for different blood tests and everyone keeps telling me im fine. But im NOT. Its ruining my life, please help
