Good morning all! I too have an many health issues and immune disorder. Has anyone ever heard of Granduloma Annular? Diagnosed with bioposy. My ANA was positive twice, rheumatoid arthritis, rash on shoulders/neck, behind ears that look like blisters with craters in them. They itched an went half way up scalp. On strong cortisone gel. Can't ever get in sun without fully being covered head to toes, and sun screen on face. I have read up on it but it's a mystery how it happens, no cure, flare ups that itch, not contagious. Has anyone else experienced this demon?
