It doesn't hurt, just pops.

 

It's not serious just annoying.

the only time it is serious is in a sport like kayaking where you have the possibility of off angle pressure to that point in a jarring motion, but then if you are going to injure that part it is just going to dislocate at that point because you weren't positioned properly.

 

I learned from an early age that it's not how many reps you can get off, it's the quality of them. 'Balance before you move', is something I remind myself of when I feel as though I'm doing something incorrectly, or my body needs to remind me. If it hurts before it burns... something's wrong.
