They should definitely warn people about that sort of thing.

I actually have a fair amount of chronic pain that rarely has an explanation. My right wrist, my hip, my head, my back, my knee, my neck and my chest/shoulders.

Only my neck and shoulder (which have gone through surgery) and my knee (injured pretty bad during sports) should still hurt the way they do. Eventually, they checked out my back. I have some interesting injuries to my spinal cord no one can explain.
