How to Identify and Treat Common Stings

Insect bites and stings usually cause transient local inflammation and, occasionally, a toxic reaction. Characteristics of a systemic reaction are urticaria, angioedema, bronchospasm, large-airway edema, hypotension, and other clinical manifestations of anaphylaxis. A small local reaction is transient and mild, develops directly at the site of the sting, and can last several days. A large (or significant) local reaction, defined as swelling > 10 cm in diameter and lasting > 24 hours, occurs in 2% to 26% of people who have been bitten or stung.
