What calms down a wasp sting?

What calms down a wasp sting includes several first aid steps that reduce pain, swelling, and itching, though severe allergic reactions require immediate medical attention. Immediately after wasp sting, wash area with soap and water to prevent infection, remove any stinger if present, though wasps usually do not leave stinger like bees, but check. Apply ice or cold compress wrapped in cloth to sting site for 10 to 20 minutes to reduce pain and swelling, repeating as needed. Elevate affected limb if sting is on arm or leg to reduce swelling. Over the counter pain relievers like ibuprofen or acetaminophen can calm pain, and antihistamines like diphenhydramine can reduce itching and swelling. Topical treatments that calm wasp sting include hydrocortisone cream, calamine lotion, or paste made of baking soda and water applied to sting to reduce itching. Some people find relief from applying vinegar or lemon juice, though evidence limited. Avoid scratching sting as it can worsen inflammation and cause infection. If you have history of severe allergic reactions, carry epinephrine auto injector and seek emergency care if you develop symptoms like difficulty breathing, swelling of face or throat, hives, dizziness, or rapid pulse, as these indicate anaphylaxis which is medical emergency. Most wasp stings resolve within few hours to few days with home care, and monitoring for signs of infection like increasing redness, warmth, or pus is important.
