sounds painful!

Not as bad as being stung on the inside of my mouth, but it's right up there.

aww so this is why they say breathe through your nose:p

If I was I'd be dead. I get stung a lot when I ride on the local MUP. Long sections have 5'+ flowering shrubbery along both sides and, when it's hot, I ride with my jersey unzipped. It sweeps up anything flying in my path and I get stung/bitten on the belly and the back. I was stung once on my last ride and twice on the ride before that. IT SUCKS.

Don't ride on the MUP?

It seems the scenery is enjoying you more than you're enjoying the scenery.

i bee allergic to penicillin

Stands to reason -- I'll bet denim is no problem for them either. Many animals have pretty tough hides. The sting has to be able to get through to have any effect.
