Hi, I was diagnosed with degenerative spine disease about the time I hit puberty. I am now 53 years old. I have no vertebral height in my lumbar spine, SI joint deterioration and (gets so boring cataloguing the stuff) blah, blah, blah. Of late, I am having some sciatic pain, but am primarily plagued by tingling and discomfort in my feet and calves. I am a long-time yoga practitioner and receive acupuncture weekly for pain management. I am in search of an exercise to relieve my symptoms. Thank you. Cynthia Tidrick
