The thyroid test is a simple blood test. That can tell if it's hyper or hypo, meaning overactive or underactive. There are other symptoms associated with the thyroid too, but it sounds like the 2 you have could be related. Get checked soon, don't let it go on for very long, the thyroid also regulates your heart rate. Thats why the palpitations. I take 1 pill a day. No big deal, even though it's forever. Good Luck
