How can I tell if I'm having thyroid problems? I have some of the symptoms that I read about but not sure if they are signs of thyroid: sweating a lot (I'm menopausal), I'm losing weight and don't know why and minor memory lapses. I have been usin prescription nasal spray for about two Meds and I have a small enlargement at the top of my chest area. Could this be something else other than thyroid or definitely thyroid??
