I had an ingrown toenail when I was trekking in Nepal, and I would have KILLED for this: my solution was to use a combination of Detol, hot water, tweezers and a set of small folding scissors to deal with it. This was, as you may divine, quite painful, and was accompanied by quite a bit of grunting and the occasional: "Just let me die, sweet Buddha, just let me ... F*CK!"

For the most part, I would go away from the group so I could manage this situation on my own and prevent the kind of gross-out you just experience watching this video. One evening I was not able to move away from the group and one of the Australian trekkers took all this in stride (pun intended) and said:

"What are you doin' over there, mate? It sounds like you're trying to pass a bowling ball."
