C.F.
My four year old daughter has chronic hives. She has been allergy tested and we have not been able to find a cause. However, hives can be a symptom of autoimmune issues so we have to have an antibody test every 6 months. You should call your doctor and at least let them know. My daughters doctor told us that some people are just "hivers" and will get them throughout their lives from different things. Heat, cold, stress, or nothing you can pinpoint. For those hives they just treat the breakouts with benadryl.
