Blisters
As a collector of blisters, this is what I do. Note: this is not medical advice and you're definitely taking some risk of infection with this method. However, I've done this a lot without problems and I've been in some pretty bad locations.

When you wake up:
However, when you start walking the next day your feet will start sweating, the blister will come undone, but it won't be quite as painful. To avoid this continue to keep the affect area 'wrapped' just to keep the skin (hopefully) in place.

Chafing
I chafe between my upper legs. Consequently, I hike my pants/shorts up so the crotch of the clothing is between crotch: the cloth is rubbing together instead of the inside of my legs. My shirt is untucked so I don't look like Urkel. This makes it cloth on cloth friction rather than skin on skin friction. This avoids chafing and/or reduces aggravating chafed areas. Wearing compression type shorts is also an option to protect chafed areas Although that may result in other parts of your body experiencing chafing.
