I personally would just continue the Synthroid medicaition,especially if your doctor told you your TSH is normal. I think your other symptoms are absolutely unrelated to hypothyroidism. You should discuss these with your doctor and maybe he/she would like to check some tests to further evaluate.

In regards to thyroid supplements, Levothyroxine (Synthroid) is the preferred treatment. I don’t know if you realize that Levothyroxine is T4 and the body converts it to the active form of T3. T3 supplementation is only used in rare circumstances and is not superior to T4 supplementation in 99.9% of patients. T3 also leads to fluctuating levels during the day. So no, I don’t think this is an appropriate option for you. In regards to natural thyroid, I do not know a single doctor that has ever prescribed or recommended this. The problem with natural thyroid is that we don’t know the potency or strength of it. Therefore we don’t know exactly how much T4 (thyroid hormone) you are actually getting. So basically the best treatment for hypothyroidism is Levothyroxine aka T4 aka Synthroid. I do not think changing your hypothyroid regimen will change your symptoms, because I very much doubt they are related to your thyroid disease. You should of course discuss this with your personal physician. I hope this helps you.
