Those stings hurt! At this point you only have to worry about infection.
Clean the wound and put on bacitracin. You might want to make a paste of accent (monosodium glutamate) and flour, which relieves the sting.
Be careful about the next sting. Sometimes the body becomes super-sensitive and a second sting may cause a severe reaction.
not unless they are bothersome and get infected of if you feel ill or dizzy swellingetc.
