In all seriousness - and I know from personal experience.
The allergic reaction will only get worse in the event of an encore performance. You are risking something nasty called anaphalactic shock.
In Summer months (particularly in Fall), I carry a nifty gaget called an Epipen - an epinephrin auto-injector. Its got so bad with me that a sting on an extremity leads to a doctor visit and a sting on the neck or shoulders leads to a trip to the ER.
You need at least:
A scrip for decreasing dose steroids taken over a period of a week
A scrip for (and excuse the spelling here and above) Flocinonide cream - another steroid.
Finally:
Always look before working in the garden or lifting anything in the woods, etc. You will develope an instinct for caution.
AND - declare war on the little yellow bastards. Find the nest if you see any of them - follow them to ground - and let somebody else deal with them.
Believe me, brother 'catter, this could be worth your life.
