Scorpion stings occur when a scorpion injects venom into the skin of a person or animal. Scorpions are found in many parts of the world, including the Americas, Africa, and Asia, and their venom can be dangerous or even deadly in some cases.

Symptoms of a scorpion sting can vary depending on the type of scorpion and the severity of the sting, but may include:

• Pain or burning at the site of the sting
• Swelling and redness
• Numbness or tingling
• Muscle cramps or spasms
• Sweating
• Difficulty breathing or swallowing (in severe cases)

In some cases, scorpion stings can cause anaphylaxis, a severe allergic reaction that can be life-threatening.

If you or someone you know is stung by a scorpion, it is important to seek medical attention immediately. Treatment may involve medications to reduce pain and inflammation, antivenom to counteract the effects of the venom, and supportive care such as fluids or oxygen.

To prevent scorpion stings, it is important to take precautions such as wearing protective clothing, using insect repellent, and avoiding areas where scorpions are known to live or hide.

A scorpion sting is caused by the stinger in a scorpion's tail. When a scorpion stings, its stinger can release venom. The venom contains a complex mix of toxins that affect the nervous system (neurotoxins).

Scorpions are arthropods — a relative of insects, spiders and crustaceans. Bark scorpions are about 2 inches (5 centimeters) long. Scorpions have eight legs and a pair of lobster-like pinchers and a tail that curves up. Scorpions are nocturnal creatures that resist stinging unless provoked or attacked.

Scorpions tend to avoid contact. If you live in an area where scorpions are common, prevent chance meetings by doing the following:

• Remove piles of rocks or lumber from around your house and don't store firewood against the house or inside.
• Keep grass closely mowed, and prune bushes and overhanging tree branches, which can provide a path to your roof for scorpions.
• Caulk cracks, install weatherstripping around doors and windows, and repair torn screens.
• Inspect and shake out gardening gloves, boots and clothing that haven't been used for a while.
• When traveling in areas where lethal scorpions are common — especially if you're camping or staying in rustic accommodations — wear shoes and shake out your clothing, bedding, gear and packages often.

Scorpions glow under a black light, so you might want to use one at night to inspect your surroundings. If you find a scorpion, use tongs to gently move it away from people.

Most scorpion stings don't need medical treatment. But if symptoms are severe, you may need to receive care in a hospital. You may be given drugs through a vein (intravenously) to treat pain.

Scorpion antivenom may be given to children to prevent the development of symptoms. Adults with severe symptoms also may be given antivenom.
