- Hives are very common, and most often their cause is elusive.
- Hives can change size rapidly and move around, disappearing in one place and reappearing in other places, often in a matter of hours.
- Ordinary hives flare up suddenly.
- Occasionally hives are produced by direct physical stimulation by environmental forces like heat, cold, and sunlight.
- Treatment of hives is directed at symptom relief until the condition goes away on its own.
- Antihistamines are the most common treatment for hives.
- Hives typically are not associated with long-term or serious complications.
