If your finger is stung by a wasp, you need to remove the poisonous needle immediately, disinfect the area with iodophor and other disinfectants, and then adopt different treatment measures according to the individual reaction. After being stung by a hornet, local redness, swelling, pain and other discomforts can generally occur, and in severe cases, allergic reactions can be caused, resulting in systemic symptoms. 1. Redness and swelling: When the hand is stung by a wasp, localized redness and swelling will generally appear. If it is only mild redness and swelling, no medication is needed. If the redness and swelling is more obvious, the bitten part needs to be rinsed with soapy water and applied with boric acid solution to relieve the symptoms of redness and swelling. 2. Pain: After being stung by a hornet, there may be obvious pain symptoms locally. If the pain symptoms are unbearable, acetaminophen extended-release tablets, ibuprofen extended-release capsules and other medications can be taken orally under the guidance of a doctor to relieve the pain symptoms. 3. Systemic symptoms: If the patient is allergy-prone, and the local redness, swelling and pain after being bitten by a wasp are serious, or there is a systemic allergic reaction, such as urticaria, laryngeal edema, respiratory difficulties and other symptoms, it is recommended to go to the hospital in time for consultation, and follow the doctor’s instructions to use anti-allergic drugs, such as loratadine tablets, cetirizine hydrochloride tablets and other drugs. Hands stung by hornets can generally be avoided, if you go outdoors where there are hornets, try to wear long sleeves, long pants, masks, hats, etc., to do a good job of personal protective measures to reduce the area of skin and mucous membrane exposure.
