In some instances, things can change quickly, with thyroid issues and in other instances, it can take months/years for them to change. There are never any guarantees.
Thank you everybody. :) I'm just upset because last they checked my thyroid everything was normal :( I was really hoping that I wasn't going to have anymore problems with it so this is just such a shock. Thank you for everyone's input!
The accuracy of palpation is only 30 % it happens now and than from every 10 people sent to the ultrasound for probable nodule only 3 actually have nodules.
Forgot to mention... I doubt seriously that you are in a life threatening situation and while there may be some discomfort, there shouldn't be any reason you can't wait until your appointment on Thursday. The breathing and swallowing issues are quite common and often feel much worse than they really are, due to the anxiety they add to the situation. That said, you are the only one who knows how you feel and if, at any time, you feel that you are in real medical distress, you should not hesitate to go to the ER.
Ask them to test your thyroid antibodies. It sounds like you might have Hashimoto's and are swinging between hyper and hypo, which is common in the early stages.
They also need to test TSH, Free T3 and Free T4 to see what your actual thyroid hormone levels are, as it sounds like you've swung back to hypo, again.
You should not palpate your thyroid -- it only makes the lumps/bumps that much worse, the more you rub and irritate it.
