The method of reducing swelling and pain after a bee sting varies depending on the type of bee sting. After a bee sting, the wound should be examined first. If there is a tail stinger, it should be removed by picking it out with a sterile needle or sucking it out with the mouth, and then further treatment should be carried out depending on the type of bee sting. If it is a bee sting, because the venom of bees is acidic, you can flush the wound with a weak alkaline liquid such as soapy water or 5% sodium bicarbonate solution to neutralize the toxin; if it is a wasp sting, because the venom is alkaline, you can use a weak acidic liquid such as vinegar or 1% acetic acid to neutralize the venom. If there is still localized redness and swelling, use glycerine lotion or hydrocortisone butyrate ointment to evenly apply to the affected area, and if accompanied by severe edema, apply 3% boric acid solution. These topical medications are good for reducing swelling and pain on the skin after a bee sting. Bee stings that are serious or highly toxic should be treated immediately and in accordance with medical advice.
