Try putting some real (not imitation) vanilla on a cotton ball and tape / hold it on the area of the sting. For some reason it significantly reduces the pain and the swelling as well as nerve irritation within seconds. It can be repeatedfor further symptom reduction.
my partner was stung by a wasp last week, it is spreading readness nad tenderness now and she has developed flu like symptoms...is this something we should see a doctor about?
Crushed aspirin will not work. A paste of monosodium glumatate (sold as accent) will relieve itching.
If you aren't allergic to aspirin you can chew one up or crush it up and mix it with a little water to make a thick paste, then cover the bite and it will help draw out the poison and relieve the pain, itching and swelling. Also baking soda works great, I have used it on my son. Just make a thick paste like mud and put it on and let it dry up real good. I have also used the aspirin thing on myself right after I was stung by a hornet. Good luck!
