I suffered so long not knowing why, I couldn't ride a horse for longer than 10 minutes before I had to get off in horrible pain, and getting off was a comedy. I wanted to ride so would try to put up with it, changing stirrup lengths,standing in the stirrups, squirming about, it was a nightmare. I have an aversion to Doctors so eventually had the bright idea to Google it (Duh! why did it take me so long). Basically it is sciatica but the pain traveled from my buttock across the front of hip down to my knee and on to my ankle not the normal sciatica route down the outside of the leg, so I didn't think it was that but it was. The exercises work. This post is to help others.HERE -opens in new window.
