I had Feldenkreis therapy and a course of Feldenkreis "Awareness Through Movement" training - found it very helpful! I am not familiar with Edgelow.
I think the key to Feldenkreis is having someone manipulate and move your body for you. It didn't seem to be a do it yourself thing. Although I did learn some good stretching exercises that I do on my own. But having someone (for example) lift your arm for you and move it about as you passively lie supported with pillows... it's just

Heavenly!!
