Bee or wasp sting is manifested by a vivid pain of the affected area, accompanied by a burning sensation which disappears quickly enough to leave room for physical signs: redness, swelling and itching skin. Severe allergic reactions can lead to the victim unable to breathe and even anaphylactic shock. The chemical composition of bee or wasp venom is very complex. It contains enzymes, peptides, amines, amino acids and other substances that the body can be strong allergens.

If local reaction bite is painful and is followed by redness of the affected area, swelling (local edema). This reaction is often accompanied by pruritus (itching) and generally disappear within hours. Depending on the injection site, swelling is stronger.

Venom is intradermal inoculation, ie, dense connective tissue of the skin. The mucosa and conjunctiva of the eye, spreading venom is faster leading to a strong swelling. After a bee or wasp stings may occur three types of reactions: local reaction, a toxic reaction closely linked to the number of stings and allergic reactions. Is the most common local reaction.

In the allergic reaction (anaphylaxis) it does not depend on the dose of venom injected. A single bite can trigger shock. A short two pins may be a risk factor in developing an allergic reaction to bee or wasp venom. An allergic person has pain and local swelling over an area greater than 10 cm, and the symptoms persist for more than 12 hours.
