I (41) developed really frequent hives, some have been very large - 4 x 5 inches, and last 2-5 days. my allergy doctor says the hives are not allergies, might be dermatographica or other type of autoimmune disease and is running blood and other tests. over last 12 months - I also developed two types of cyst - one on face, one on knee, and last 6 months developed chronic hives. My dad (67) had two autoimmune disorders in the last 3 years (his kidneys nearly died, some kind of bulbous that affects the skin). There is no lupus, rhumatoid, or thyroid conditions in the family. Should I have told the doctor about the cysts? does this sound like specific autoimmune disease?
