How to reduce swelling after a wasp sting

After being stung by a hornet, to effectively reduce swelling, quickly move away from the hornet to prevent further stings. Then, gently apply cold compresses using cold water or ice packs to the affected area, which helps alleviate pain and swelling. If possible, wash the sting site with soapy water to neutralize the acidic substances released by the hornet. Apply an anti-allergic or anti-inflammatory ointment, such as hydrocortisone cream, to relieve redness, swelling, and itching. If symptoms are severe—such as persistent swelling or signs of systemic allergic reactions—take oral antihistamines like chlorpheniramine or loratadine promptly and seek medical attention immediately. Avoid scratching the sting site during treatment to prevent worsening infection. Monitor your physical condition closely, and seek medical help if any discomfort occurs. With timely and proper care, swelling from a hornet sting can be effectively relieved.
