One more thing to think about or to get checked out:

-- have a physical therapist check out the length of both of your legs.

In my case, one of mine is slightly shorter than the other. My son had been telling me for YEARS, I was "crooked". It can throw a lot of stress in the low back area. I have problems in L1-L2-L3-L4-L5 and L5 is fused to the pelvis. All of that causes havoc in that area 'cause you're not "balanced". I, too, get "****" pain when I sit too long -- especially on non-soft seats.

Good luck.
