What's the best way to treat a wasp sting?

[ssd]

Anyone know?

Dab it with vinegar, put a cold compress on (or a bit of ice in a teatowel) and take an antihistamine.

If it's anywhere near the mouth or eyes go to the GP or A&E if the swelling gets very large. If it's in the mouth go straight to A&E.

Lots of anthisan cream. (It's an anti-histamine cream available over the counter)
