Hi
There is a common skin condition called hives or urticaria, which causes red and sometimes itchy
bumps on your skin. Hives can occur anywhere on
the body such as the trunk, arms, and legs.
Hives are usually allergic (food, medication and insect stings) but may also be due to infections and stress. Many a times no specific cause for them is ever found.
They usually go away on their own.
