Bee sting.

Venom allergy is the condition where an individual experiences a potentially dangerous allergic reaction from the sting of an insect, including honey bee, wasp, yellow jacket, yellow hornet, white faced hornet or imported fire ant. In addition to carrying epinephrine, it is recommended that individuals who experience a dangerous allergic reaction after being stung should undergo allergy evaluation to determine which types of stinging insect they are allergic. When allergy testing is positive, patients can often be "desensitized" to stinging insect venom, so that future stings are far less likely to cause a problem. This is a simple and potentially life-saving treatment that is covered by almost all insurances.
