After you have been stung by a bee, you can reduce the swelling and itchiness by general treatment (ice pack, topical application of alkaline or acidic liquid depending on the species of bee) or medical treatment (medication, debridement, etc.) after removing the bee stinger. 1. Immediately look for the bee needle in the stung area and remove it. 1. Apply ice: After being stung by a bee, apply ice to the area for about 10 minutes to reduce swelling and avoid frostbite caused by prolonged icing. After being stung by a bee for 24 hours, you can apply localized hot compresses to promote blood circulation and reduce swelling. 2. Local application of alkaline liquid: Since the venom of bees is acidic, you can apply alkaline soap locally to neutralize the toxicity and thus reduce swelling and itchiness; if you are sure that you have been stung by hornets (wasps), you can use vinegar to wash the compresses since the venom is alkaline. 3. Medication: After being stung by a wasp, you can apply some ointment to reduce inflammation, swelling and itching under doctor’s guidance, such as erythromycin ointment, budesonide cream and other topical medications, or you can take anti-allergy medications, such as loratadine. 4. Cleansing treatment: After being stung by a bee, if the scope of the sting is relatively large, the symptoms appear to be more serious, and an abscess is formed under the skin, it is often necessary to make an incision and drain the wound. It is also necessary to carry out intravenous anti-infection treatment under the guidance of the doctor to avoid bacterial infection, commonly used drugs such as cefuroxime. 5. If there are serious symptoms such as chest tightness, confusion, rapid heartbeat, etc., you should be sent to the hospital immediately for emergency treatment. Note: After letting the bee stings, do not scratch with your hands to avoid inflammation aggravation, please seek medical treatment in time when serious symptoms occur.
