Hives are a collective term for the allergic reaction called urticaria. Hives are characterized by a sudden outbreak of swollen, pale-red bumps called as welts on the skin. It usually lasts for 6 to 24 hours and does pose any health threat if the severity is normal. Hives typically occur as an allergic reaction to a substance, such as food, body products, etc., that you encounter or swallow. The non-sedating variant of antihistamines is mostly used for mild hives treatment. There are other conventional hives treatment as well, and if you are inclined to oriental medicine, ancient therapies, and home remedies, then you will not be disappointed either.
What are hives?
When our body comes into contact with an allergen, it releases a protein called histamine as a part of its defense mechanism. A significant amount of histamine leads to severe itching, swelling, and redness.
Hives rashes usually have defined edges, and they appear in varying shapes and sizes. Though wretched hives are considered harmless, and they tend to disappear within 24 hours. Also, hives are not a contagious disease.
What are hives symptoms?
Common hives symptoms are swelling of skin into pink or red welts or patches. If hives have occurred in reaction to some food, welts will occur either single in number or a group.
Welts can form a pattern with defined edges. The most common welt type is circular with a pale center and a red halo. Sometimes small welts join together to create a large area of raised skin.
If the allergy persists, another group of welts will appear at a different location after the first pattern disappears. In case of an extreme allergic reaction, angioedema can occur, which can cause severe swelling.
