I fired my doctor of fifteen years and went to a new one. its a long story, but basically my old doctor got too busy for me, and was no longer giving me quality care or addressing any of my concerns. This new doctor put me through a variety of tests and besides telling me that I have lungs that are 159 years old- she diagnosed me as having hashimotos' disease. Apparently my own immune system has attacked my thyroid. anyone else heard of it?
