Local swelling, even dramatic swelling, is normal and not a sign of allergy. Swelling often takes 3-4 days to resolve. Bruising and itching often are associated with this swelling. Bee and wasp stings can become infected and therefore, all sting sites should be washed with soap and water. Signs of infection include a red streak running up the extremity, fever or any discharge from the sting.
Infection requires prompt medical attention.
Bee sting allergy produces sudden severe symptoms that usually occur within minutes following a sting. Signs of a severe reaction include flushing and anxiety which are almost always present. Facial swelling, especially around the lips and eyelids may be present. The victim may have difficulty breathing, feel as if the throat is closing, or may lose consciousness. These symptoms require emergency action.
