Re: lab results, but still have symptoms :(
Hashimoto's doesn't take one from total health to severe, debilitating illness in just 3 weeks.
And thyroid hormone doesn't relieve symptoms the way aspirin relieves headache. It replaces the deficit of the body's natural thyroid hormones so that healing will occur and the body will function the way it was meant to. I believe your endo is correct in not rushing to treat based only on symptoms without more supporting evidence from labwork. That's not to say your thyroid isn't sick, just that the onset of your symptoms doesn't jibe with that.
If you were truly healthy 3 weeks ago, you should investigate other causes for your illness. Lyme disease, for example, has many of the same symptoms as hypothyroidism, and their onset would happen in a much faster time frame. Do you frequent the outdoors where you'd have been exposed to deer ticks?
Wishing you wellness.
