Around 10 years ago i was diagnosed with hashimotos diease and my tsh level was 13. i recently attempted to get back on medication because i feel awful but my tsh was 3.80. does this mean i don't have hashimotos anymore? why do i still feel sick?

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your TSH may be spuriously low if you are taking Biotin supplement, or if the level is so high that it is beyond the linear range of the assay. Wish you good health!

Correlating thyroid function with symptoms is very difficult in most cases. Hashimoto's is an inflammatory problem and can go on for years but if TSH and other tests are normal may have stopped or burned itself out. Discuss with your Drs.
