Mary (USA) on 08/05/2019: Sciatica, cause is the arch of the foot has fallen.
Remedy is simple - use arch supports. I use walk fit because it has 3 lifts low, med, high, but the trick, if you have leg pain, is to install a dime size thin magnet between the lift and the support. As you know, magnets do not do the healing but iron in blood is attracted to the magnet iron brings with it oxygen and oxygen heals.
Since it is a static magnet it may take a few weeks before one sees improvement BUT, if you take statins forget everything I wrote as statins cause the leg problems.
