Isaac, I think you made some good points, but there really are some guidlines that can be followed to prevent injury. I personally find that I feel worse after an hour lifting weights than I do after a well executed dive. Sure, you feel tired and a bit drained after a dive, but after you finish your surface deco, you should be ready to go! Trey talks about the half hour rule- if, after a half hour, you don't feel up to a five mile run, then you didn't do adequate deco (or you're not in good enough shape for the dive you did). You have to realize that just walking around induces a certain amount of trauma on the human body, so you are right in saying that all diving involves some injury. That's OK because your body is designed to deal with that. Its when you overwhelm your body's ability to cope with injury that you get into trouble. In terms of deciding whether or not a particular ache or pain is DCI, there are a number of ground rule that can be applied. However, I think a more rational approach is that if it goes away, then sit back and analyse what happened. Take the pain and use it as a warning that you did something wrong. Maybe it was DCI, maybe it was overstressing joints that you hadn't adequately trained before the dive. Think it through, talk to a medical advisor if you're not sure, then modify your training or deco procedures to prevent it from happening again.
