10 Symptoms of Hives
Reviewed: Dr. Gromatzky
Symptom #6: Frequency Of Appearance
When a rash arrives, it is usually there until the condition causing it has been treated, although the rash itself can sometimes be treated before the cause. In most cases, the rash will resolve in just a few days, but some conditions can cause rashes that stick around for longer.
Hives are quite unusual, though, in that they can disappear and reappear for no apparent reason. They will usually disappear altogether within 24 hours or so but they can come and go several times in that period. In severe cases, though, hives can remain with a patient for months or even years.
