Hello Ester. I am suffering from some pretty significant groin pain in my right hip constantly for about 1.5 years now. It has come and gone but is pretty severe now. I have been convinced that it is the Iliospoas muscle being tight and have spent alot of time stretching it etc but to no avail. Although I have had your book for a while now, I have only just started to work on the glide walking and when I push off hard with my glute musles, I feel a significant stretch in the right groin area (where it hurts). I am just curious to know if I should continue to work on this technique or if I am actually making this worse. Am I over using the psoas muscle in doing this? Any suggestions on how to min it's work while still not using the quads? I am very frustrated and a little depressed that this is such a problem for me and I truely think it is related to my ongoing low back pain. I want to fix it once and for all!!! thanks in advance for your response.
