Here’s a rewritten version of the article:
What it looks like: A wasp sting typically causes immediate, sharp pain followed by redness, swelling, and a burning or itching sensation at the site. A raised welt often forms, and you may notice a small white spot in the center where the stinger pierced the skin. For most people without a wasp sting allergy, these symptoms are mild and begin to fade within a few hours.
Symptoms to watch for: In some cases, a wasp sting can trigger a stronger reaction. Signs of a mild allergic response include increased redness and swelling that worsens over the next two to three days, as well as nausea or vomiting. These symptoms usually resolve on their own within a week, but it’s a good idea to contact your doctor if your reaction seems more intense than usual.
For individuals with a severe allergy to wasp venom, a sting can lead to anaphylaxis—a potentially life-threatening condition. Warning signs of anaphylaxis include swelling of the face, lips, or throat; hives or itching in areas away from the sting; difficulty breathing (such as wheezing or gasping); a rapid or weak pulse; nausea or vomiting; and loss of consciousness. If you or someone else experiences any of these symptoms after a wasp sting, seek emergency medical attention immediately.
