First aid kit threads are some of my favorite on this forum and there hasn't been one in a while. I would like to get a survey of the most common health problems (and some serious problems) people have faced on the trail. I'd like to get a better idea of what I should expect out of my FAK. I haven't ever really had to face many issues on the trail (me or people in my group/met). My list is maybe:

1. exhaustion/dehydration
2. minor cuts and scrapes
3. blisters
4. splinters

1 isn't really an FAK issue, 2 is pretty minor (but I carry band-aides), for 3 I carry mole skin and donuts, 4 I have tweezers. What have other people faced? What do others think of as important health problems that you should be prepared for by carrying something in your FAK?

Other things I think it is important to plan for:

1. major cuts
2. sprains/strains
3. broken bones
4. diarrhea (pepto)
5. inflammation (iboprofin)

and things I think about preparing for:

1. nausea
2. headaches
3. allergic reactions/ poison ivy
