What treatments lower swelling for wasp stings?
The first step to treating a wasp sting is to remove the stinger, states WebMD. Avoid squeezing the stinger, as more venom may enter the body. Instead, use a fingernail to scrape the stinger off, or use tweezers. After controlling the swelling, take a pain reliever such as acetaminophen or ibuprofen. Children under the age of 18 should not take pain medications. Apply an antihistamine or calamine lotion to reduce itching. A baking soda and water solution also helps with itching.
