Do you have prefolds? I just toss a prefold on my son like a blanket when I want to let him go without diaper for awhile.
It sounds infected for sure. Do you have any health food stores nearby? Like Trader Joes or Whole Foods or even just a little local place, you should look for some of this:
I used it on my vulva after having my first baby because I tore really, really bad (3rd degree tears) and it felt great. It doesn't smell good but it is an amazing product.
