Re: still confused whether I'm Hyperthyroid or not..
There is a disease called Graves that causes hyperthyroidism. It can come on quick or slow, and you can have signs of hyperthyroid without having abnormal labs if they aren't checking the right ones. You may also need your antibodies tested, TSI and TPO, are ones they will look at for Graves. Graves is an autoimmune disease that causes hyperthyroid plus a few other things. Alot of people report these problems long before TSH and Free T4 are out of range. The antibodies will make you feel like crap if they are high. Even after I have had my thyroid killed off with RAI(radiation) I still have high TSI, showing that the Graves is still active in my body. The normal range for my TSI was >130 and my last test was 296. I still have normal labs for TSH and Free T4(but mind you I also take meds for a hypothyroid now). Some people can have a hyperthyroid and only have there Free T3 effected as well, causing hyperthyroid in them. I would ask for antibodies testing and a Free T3 test, if these come back ok, you might need to look into other things. I myself suffer from these same symptoms but they were brought on by diabetes! So I hope you find something out soon, and start to feel better. I would never say that the thyroid couldn't be the problem because so many people suffer from it long before they get out of range, for you just a little bit could make you feel this way. So keep on having the levels checked, if it is the thyroid soon these levels will be out of range, but by then you may feel even worse. All you can do is keep the doctors checking. One more thing about this, do you have a family history of any thyroid disorder?
