Then the patient can maintain the effect with the much safer antihistamines, since steroids have significant side effects if used long term.
Neither the patient nor the doctor can determine the cause of the hives.
Patients will often say, "It has got to be something causing these hives." The truth is hard to accept for some patients.
These are welts; pink swellings that come up on any part of the skin.
They itch and each individual hive lasts a few hours before fading away, leaving no trace. They can be pea sized or join to cover broad areas of the body.
Some have autoimmune thyroid disease, vitiligo, swollen joints, or certain abnormalities in the blood (especially the ANA test).
A new treatment has recently emerged for autoimmune urticaria.These areas may develop a swelling that is frightening in appearance, but usually goes away in less than 24 hours. In many cases, a single attack of hives is due to an infection or virus and these go away within a few days to a few weeks.Some people get repeated attacks that occur as an allergic reaction to a variety of things (foods, most commonly nuts, chocolate, fish, tomatoes, eggs, fresh berries and milk, insect stings, and medications).Certain people can develop recurrent hives from sunlight, cold, pressure, vibration or exercise. If hives develop from scratching or firmly rubbing the skin it is called dermatographism.It is the most common of the physical urticarias and it affects about 5 percent of the population. This condition sometimes also occurs along with other forms of hives.Some people react to anything that makes them hot or sweaty with hives.
