Re: What Causes Chronic Uterica
I found out I have cold urticaria, but was first dx as chronic idiopathic urticaria. Most of the time, no known cause can be found for chronic urticaria. Unlike acute urticaria which is mostly caused by food allergy. CU can be from food, physical urticaria(cold/heat/pressure...etc), infections, autoimmune disorders, some medical conditions, etc. It's hard to identitfy but you can help yourself and your doctor by keeping a diary. Record everything down, place, time, date, weather, what you are doing, what you ate, things you come in contact. It's not easy to do so but you might find something out of it.
Usually antihistamines are good enough to keep the hives at bay. Some need more than 1 type of antihistamines, or I call a combo to find relieve from hives.
