Biking with a blister?

[VeloVT]

Ok, , I'm outnumbered by people who know more than I do!!!

But I do want to know: ladies (RNs), what should you do about a painful blister if taking time off is not an option? For running especially, an intact blister can make it pretty difficult to train. What's the best thing to do if it's very uncomfortable but you don't want to wait for it to go away on its own? Also, why is alcohol a bad disinfectant and what would be better?

Thanks!!!

Sorry if my last post sounded arrogant.
