Hippocrates I am going to try your method of pressure, stretching and the Biofreeze gel. You say about keeping my knee over my second toe but when riding, my toe should be at about a 40 degree angle so my toes are to the out side of my knee when in the stirrup.

Hallamshire, what do you mean by overly extended lumbar spine? Upper body position always varies from sitting vertical, to extremely forward (as over a fence). Also, the pain occurs from fast walking and or step aerobics as well.
