I am both a physiotherapist and a common SI sufferor pain.

The pad with its own accompanying this area and an area competitors who do not use a pillow. I found the pad to provide only very little improvement over the band itself.

The cushion adds several major part of the area is visible with clothes and affects how clothes fit, making their clothes unacceptably tight.

The cushion also leaves a permanent increase in non-skid beneath the surface of the belt.

It will probably cause damage if used too long. I wear only my pillow in the days when my pain is so horrible that I will try anything for relief.
