Replying to Ask Dr. NS: Lower/Mid Back Pain

Being a 29yr old avid park skier, I've been feeling some pretty rough aches and pains lately, specifically in my lower/mid back. Its in a really awkward spot just below my shoulder blade ('scapula' I think?) and towards the center. Feels like a pinching and then spasm sensation along those two long muscles that run down the sides of your spine; basically impossible to stretch from everything I've tried. Tried the foam roller as well, dunno if mine is too firm but it didn't seem to provide any relief either.

I've got an appointment with a PT tomorrow, but before I go in I was hoping for those with some experience with similar issues to share their story. How do you stretch and treat your back issues? Photos/pics encouraged, explaining stretches verbally can get rough
