The answer to 'wasp bites' is that wasp stings can cause pain, swelling, redness, and itching. Wasps have a stinger that injects venom when they sting, which leads to these symptoms. Most wasp stings are not serious and can be treated at home, but some people may have an allergic reaction that requires immediate medical attention.
To treat a wasp sting, first remove the stinger if it's still in the skin. Then wash the area with soap and water, apply a cold compress, and take an over-the-counter pain medication like ibuprofen or acetaminophen. Antihistamines can also help reduce swelling and itching. If you experience severe symptoms like difficulty breathing, rapid heartbeat, or dizziness, call 911 or seek emergency medical care right away as these could be signs of anaphylaxis, a life-threatening allergic reaction.
