I was stung by a red wasp twice 24 hrs. Ago. The one on my left wrist is itching, red and has heat coming off it. The one on my left leg is swollen, red, hot, and the site is still open. Already cleaned both, placed a baking soda/water paste on it. And Benadryl. What else could I do to get rid of the pain, swelling, fever, and redness?
