Snakebite
A snakebite is an injury caused by the bite of a snake. Most snake species are non-venomous, but bites from venomous snakes may result in envenomation, in which venom is injected into the victim. A common sign of a bite from a venomous snake is the presence of two puncture wounds from the animal's fangs. Envenomation may cause redness, swelling, and severe pain around the bite, which may take up to an hour to develop. Vomiting, blurred vision, tingling of the limbs, and sweating may result. Most bites are on the hands, arms, or legs. Fear following a bite is common with symptoms of a racing heart and feeling faint. The venom may cause bleeding, kidney failure, a severe allergic reaction, tissue death around the bite, or breathing problems. Bites may result in the loss of a limb or other chronic problems or even death.
