Doris, try taking some antihistamine like Benadryl & a Tylenol. One for the poison, one for swelling & pain. You can also try soaking a pad in Witch Hazel & hold it on the places for a couple minutes several times per day.
Now, next time you get stung by any kind of wasp or bee or hornet. A) Scrape the stinger out --- do NOT pinch it to pull it out; that will just squeeze the rest of the poison into you. Use your fingernail to scrape the skin & remove the stinger & it's attached poison sac. B) Get some household ammonia on the stings as quickly as possible. The ammonia breaks down the protein in the venom thereby rendering it less toxic. It WORKS!
