For minor problems with the back, there are ways to decompress the spine without outside assistance.
Find a table or a bed that is higher off the floor than the height of your torso. Then lay face down on the edge of the surface and make sure that the tops of your thighs are supported while your entire torso hangs to the floor. Relax your back, your arms, and your neck. Allow your body to go completely limp. Breathe deeply and remain for several minutes. When you emerge, you'll feel taller and less tense in your spine.
Or, as my husband suggested last night, tie a rope around your ankles, hoist yourself up to the ceiling, and hang like a bat!
Inversions are safe and healthy for those with minor back problems and use gravity to create space between vertebrae...
Anyone else have ideas?
