Lying (around) in Wait

So I've had back pain for about 8 months now -- I am reasonably sure it's the result of a jammed or torqued sacroiliac joint and some exceptionally tight muscles around it but I'm about at the point where I want to get it looked at because it's annoying the hell out of me, and it's unmotivating and debilitating. There are days and times when it feels worse than others but overall it's always there. It makes me not want to practice Yoga because it hurts! It makes me not want to exercise, dance or otherwise move because it hurts! And it sucks! True, I have empathy for those with chronic pain and physical limitations but frankly, I thought I had a good enough amount of empathy before. I don't really believe it's not going to resolve itself, but it's a curiosity to me. My personal orientation is that physical problems have psychological roots so I'm wondering what might lie beneath. Stay tuned.
