I have had this one and off for over 10 years ..the first time after over a year and so many medications that I can't count them a Doc friend of mine said "get a biopsy of the hives" well I did and found out it was being caused by a baceria I was put on dapsone and it cleared up. If I have a bad break out now I go have a biopsy done that is put under ultra violet lighting .. Hives can be caused by bacteria, viruses, funguses so many things I am also now more aware of the different cells in the body and what each means I also strongly suggest that you have tests for your Iga, Igm,Igg and so on. Learn abt imminedefiency disease that can be related to hives I am on Gamma Guard and it is working for now but I believe if a patient has a terrible breakout that isnt working with any meds have a biopsy done also there is a great doc at Mt. Sini that totally understands immunedeficiency diseases We don't just have the hives the more predisone they gave me the worse they got because my body had a bacteria growing in my skin
A warm compress will relieve the itching. Remember the rule heat relieves itching, cold relieves pain. i wouldn't worry too much, but if the redness spreads there might might be an infection or lasts more than another two days you should consult a physician.
