I've been dealing with lower pack bain for nearly 10 years. Had two pain injections into the area, gave some relief for a few months, then back to square.
Come to find out (just recently), it wasn't my spine -- it was a muscle group along the glutes and hips.
I'm a huge video game player, and it's nothing to sit in front a computer screen for hours at a time. When fitness experts say that long periods of a sedentary lifestyle can hurt your body, THEY'RE NOT JOKING!
Please -- watch this video. These stretches/exercises have helped SOOOO MUCH over the past three weeks -- I feel like I can get back to doing the activities I was doing 15 years ago.
