What causes skin hives?
Skin hives can be caused by a variety of factors, including:
- Allergies: Foods, medications, insect stings, and pollen are common allergens that can trigger hives.
- Infections: Viral or bacterial infections can also cause hives.

How are skin hives treated?
The treatment for skin hives depends on the cause and severity of the condition. Some common treatments include:
- Antihistamines: These medications help to block the release of histamine, a chemical that is involved in the allergic response.
- Corticosteroids: These medications can help to reduce inflammation.
- Avoiding triggers: Identifying and avoiding the triggers that cause your hives can help to prevent future outbreaks.
If you are experiencing skin hives, it is important to see a doctor to determine the underlying cause and get appropriate treatment.
