Have been to several dr.'s for Unexplained angioedema. Started beginning of July. Happens mainly in the evenings, occasionally during the day. It has changed from occasional (4 - 5 x's a month) to more regularly (2-5 x's pr week), the welts and /or swollen areas use to go away after 2-4 hours and now lasts 6-24 hours. Mainly happens at home, but has happened outside of house. Never at work. Body welts / hives are extremely itchy - lips get numb and tingly and swell. Body hives make me anxious from non stop itching. I take adderall during the week, benedryl most nights - it happens both off and on these medications. Allergist seems unconcerned. Said it should run it's course and could last up to a year. Under a lot of stress. He doesn't think it's stress related. Said most likely auto immune. Should I see other dr. Or not worry about it
