Question: hives and facial swelling when sweating

 Quinn94 - Mon Dec 14, 2009 3:28 pm

My 17 yr old daughter gets extremely itchy, breaks out in hives, and her face swells when she sweats, even if it's not profuse sweating. It's worse on her arms and legs, but her neck and face can be affected too. It started when she was 15, and changing laundry detergents hasn't helped, is this an allergic reaction? Is there a way to test her or her clothes when it ISN'T happening?

User avatar Hello,Hives that break out after sweating are known as cholinergic urticarias which are not related to the common hives which are allergic.These are known as physical urticarias in which there is release of chemicals in respose to, like touch,pressure,vibration or sweating.There is no specific treatment but to avoid precipitating factors like sauna baths,heavy workouts,hot foods and stress.Antihistamines do contol symptoms but not curative.Many would out grow these symptoms in time.Best wishes.
