Hives (Urticaria) occur as a rash or welts and are often itchy, or may burn or sting.

 

They can appear anywhere on the body and may last minutes or days.

 

Hives can signal serious problems, especially if accompanied by difficult breathing.

 

Medications like aspirin or penicillin; foods like eggs, nuts, and shellfish; food additives; temperature extremes, and infections like strep throat can cause hives.

 

Removing the trigger often resolves the hives.  Symptoms can be treated with Zirtek liquid.
