but no really, I didn't read all the responses.
just to throw in my .02 about nasty blisters:
I get them all the time. I have never once done anything special about them. they never get infected, and I'm a dirty sumbitch. like, no, really, a DIRTY sumbitch.
whenever I get a blister, I promptly pop it because I fucking hate blisters, rip off the skin that covers the blister, and the raw skin is painful, but IMHO it's better than dealing with the damn blister itself. they always just dry up and turn into scabs. nbd.
this is not medical advise, it's just what I do, and it has never failed. fuck a blister. pop that motherfucker, rip off the skin, and deal with the raw skin hurting for a day or so.
