My suggestion is to lie on the floor on your back with your legs (calves) resting up on the sitting surface of a chair or low bed. You can use a pillow under your head for comfort. What this does is put one in a sitting position, knees bent at 90 degrees, and decompresses the lumbar and sacral areas. Chiropractic, physical therapy, gravity boots, and those inversion tables accomplish the same thing through traction. Before going to bed, I used to fall asleep on the floor doing this. Straighten your legs while doing it, arc them to the left and right like a metronome, then put them back down. Feels great.
