Here is some additional information:

I first injured my back over a year ago when I was 21 by attempting to lift something I shouldn't have, so the degeneration isn't age-related. I have some pretty bad lower back pain and stiffness. It's a constant pain that only gets relieved when I lay down, and even that relief is starting to go away. Whenever I lift my right leg or move it around at all (as in walking, etc), there is pain in my back, but I'm not sure if it's sciatica or not. It's hard for me to tell.

I've been told to do stretches and exercises for months, but I haven't felt any relief from those things.
