What causes cold urticaria and solar urticaria in the same patient? Could it be an hhv6 infection/encephalitis she had at 18 months?

Urticaria: It's not known why these two conditions occur. They may be inherited or caused by a virus.

This is my 15th day of 15 day treatment w/Bactrim for sinus infection.  15 min. after taking next to last pill in bottle, got hives.  Related?

So getting hives on the last day of Bactrim (sulfamethoxazole and trimethoprim) therapy is suggestive of allergy to the medication. Please inform your health care provider of this reaction. ...Read more
