I was diagnosed via MRI with severe spinal stenosis and ruptured vertebrae. I am 69 years old and have been in good health most of my life. Sciatic symptoms crept up on me over the last few years as I have aged. I started the Lumbar Spinal Stenosis Boot Camp exercises in Dec 2014 and did the exercises twice a day for 6 weeks. I started to notice some improvement almost immediately. I plan to continue on a very consistent basis going forward.
