Willow bark tea will relieve pain as it has same compound as aspirin. But, taking up space for minor pain isn't going to happen with me in a survival pack.

But, then I don't have a bug out plan, I do have a bug off plan. LOL

If I was going off in the the wilds for a month or so and could only take say 20# of gear my list above would be in it. If I had room, I would add a piece of gill net though, it will also catch small animals, birds etc. I can live through minor pain, can't live without water and food.
