Sting from a Wasp Underlying Cause
Most bee stings cause irritation and inflammation of the skin. Sometimes, the venom can cause an allergic reaction. This is often referred to as a hymenoptera envenomation.
Allergic reactions occur when the immune system overreacts to a harmless substance, called an allergen. The immune system is made up of special cells, called white blood cells, which fight infection. When an allergen is present in the body, white blood cells recognize the allergen, and release chemicals into the bloodstream. These chemicals can cause inflammation of the skin, nose, throat, lungs or intestines.
