solar urticaria symptoms
In some people, solar urticaria reoccurs and becomes a chronic condition [source: Asthma and Allergy Foundation of America]. People with solar urticaria also might feel sick. Other symptoms can include headache, nausea or fainting [source: Baron]. You should consult your doctor if the rash persists or worsens, or if it covers a large area of your body that was protected by clothing.
Solar Urticaria Symptoms. Solar urticaria is a photodermatosis, i.e., a skin condition precipitated by light, which causes red, itchy bumps to appear on the skin. Sunburn, lupus and polymorphous light eruption, i.e., red blisters and pimples, are other types of photodermatosis.
Dr. Barbara Stark Baxter Dr. Baxter. Solar urticaria: Solar urticaria is a type of hives that occurs when the skin is exposed to the sun. The hives are not necessarily on the sun-exposed skin, however. They can come out on skin under clothing. The symptoms are itching and red bumpy rash that looks and feels a bit like a bunch of mosquito bites, but without the puncture of the bite.
