How long will it take thyroid medicine to start making you feel better?

Every person is different...and reacts to thyroid meds differently...blood work is important, as is a functional doctor that will order the correct tests to evaluate your factors, such as hasimoto's, which is auto-immune and could lead to other auto immune diseases...symptoms may still be present, even if your blood TSH is showing normal....that is why a functional dr. is so important to get you where you feel good...
