Hi, Another person wrote to me as well. She had an overactive thryroid which is now under control but came down with pd afterwards. She never connected the two. As I told her, I haven't found anyone in the medical community that will admit that this can happen. Have you? Did your symptoms last or did they disappear? My husband has had pd since. If we can get more responses maybe we can get a stop done to that test. Or perhaps it would trigger some kind of research as to how this disease gets started in the first place. Keep in touch. And, thanks for responding. I will definitely stay in touch.
