not unless they are bothersome and get infected of if you feel ill or dizzy swellingetc.
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.
