Bex, re: thyroid, it would be good if you could get a dr. who is, at least, somewhat holistic - many endocrinologists are not. Some wonderful naturopaths will prescribe thyroid meds with no testing - just by your symptoms. Also, from what I hear, blood tests for thyroid are not as accurate as as the new saliva tests. There is a saliva test out there that will test thryroid, adrenal and sex hormones because all these hormones affect each other. Many naturopaths prefer this. You can get this test cheaper without a dr's requisition at the canary club which I will shortly send you the website address for. I can't remember - do you live in the US? Anyway, this test takes a while, so, since it seems you should be tested immediately and get results ASAP, perhaps this test could be useful for the future. With the way you sound, if it is thyroid, it should show up on any test. And, by the way, the new acceptable levels for TSH are anything below 3.0. Most labs and drs. are not following the new levels and think that as long as you are under 5.0 you are o.k. NOT SO! Please get tested. Thyroid problems - either way - can be fatal.
