Couldn't agree more.
I would add, taking pain pills can lead to really bad judgment because pain is telling us something is wrong, painkillers are overriding that message.
If we can't fix it with Advil, Tylenol or Bayer's enough to get back to base .. then we are in real trouble and pain isn't the issue.
Methodical medical treatment, within our ability, prior to a doctor's or other intervention is our job … not killing the pain. (Old Indian Trick.)
I broke my wrist once and kept working. After about 1/2 hour I had taken aspirin or something. Complicated the treatment because I didn't stop and take care of it when it first happened.
Although morphine/codeine type painkiller was great by the time I went to the M.D. with a wrist as big as a softball. Admire your past; you put it 100% well. Anyway, the answer to the issue is … IMO … if you are worried about pain then take morphine or codeine with you, but watch out for the side effects and the reliance on the meds can severly dim judgment.
PS: Thomas K, I have tried that and there is a stronger effect from a combination of common, low level pain killers, but as another poster said blood thinning is an issue. I would chose 2 extra strength Tylenol and 1 stronger Advil. If that didn't do it, I'd be wondering about the benefits of the EPIRB devices.
I don't know about the blood thinning characteristics of either, but they must be better than aspirin, because it is contraindicated for severe wounds and internal bleeding, especially. Although it is good to thin the blood, prevent clots and heart attacks.
(In my training the main issue with morphine is that, for example in a desert environment, it dehydrates and has a curve which means things can get worse without more. Therefore, it is only a drug of choice if your mind cannot take the pain or your situation requires you to do things that would not normally apply in a backpacking incident where you can calm your mind and self-treat your body.)
