Pulled a Back Muscle

I've got a sharp pain in the right side of my lower back. It hurts while stretching and breathing deeply. I'm certain it happened while lifting weights last night. I'm going to try to swim today and see how it goes. This is a very minor injury, however, very annoying to train with.

I'm going to get to practice early, stretch it out and hope for the best. I'm lucky that I rarely injure myself, and even when I do, it's something silly like this. This is yet another testament to how important stretching is. I doubt this would have happened if I made ample time to stretch daily.
