... on the seventh day He rested ... on an inversion table! And it was good.
I'm no expert but everyone I ever knew (personally) that claimed to have sciatic pain was cured by new shoes. Worn out shoes are the bain of foot, ankle, knee and lower back health. A few had legs slightly different in length that was easily noticed by the radically different wear patterns of thier worn out shoes (and 'cured' with orthotics to correct for the length discrepency). YMMV
P.S. No, I do not sell shoes ... or inversion tables.
