I had a doctor tell me that because I had mild DJD in my spine that I should never do impact exercise again. And that type of exercise is my favorite to do (I am a gymnast). He said, "You will have to stop sometime, so you might as well stop now before you make it worse." I did stop for a little while, and my pain lessened, but never went away. The comment stuck in my mind because every time I did my favorite activity I felt guilty like I was making myself worse and making a stupid decision, even though my pain didn't always happen when I did gymnastics, and it would happen when I was doing other things. Still, I thought that I was possibly hurting myself and that is stupid and short sighted and immature.
