What should we do after a wasp sting on the head? Need an expert advice?

GREETINGS, is any part of the stinger still in the scalp? You have to get it out. For any bee sting in the hair/on head, ice is important, ice 10 minutes out of every hour until the throbbing stops. Don't wash your hair tonight and if you can avoid it for 48 hours as the shampoo is gonna irritate and sting. You might want to try baking soda paste as that is good for stings and swelling. Take an antihistimine tablet such as benedryl to help with swelling and ibuprofen or tylonel for pain. Watch for any allergic reactions to the bee venom such as face reddening, breathing problems, excessive swelling, dizziness, etc. If any allergy symptoms develop go to the ER immediately.
