Was beginning to feel slightly better though not symptom free. Latest bloods TSH 3.8 (0.34-5.5), FT4 9.1 (7.5-19), FT3 4.9 (3.8-6). Am on 50mcg Levothyroxine and Vit D and iron. I have Hashimotos. Fell horribly ill and spent 4 days of Easter in bed - sore throat felt a bit like tonsillitis but lower in throat, absolutely no energy hardly able to move. Although tiredness has improved I still have a horribly painful throat - can't sleep, feels like someone is strangling me! What is this and can I do anything about it?
