"I also have several autoimmune diseases. "Autoimmune Disease" is like a large umbrella term, and there are over forty diseases underneath that are linked in some way. The possibility of developing more than one is very high. Personally, I have the Hashimoto's, plus I have developed Reynaud's Disease in my hands and feet, I have had positive results for Lupus, and also had positive results for Rheumatoid Arthritis. So far I am on no other medication (thank goodness) and am coping with lifestyle changes."
