I broke my spine in 2004. Since then I continued with PT and have had different spinal blocks and have had prolo-therapy twice before. Now in 2012 I was in a lot of pain with my SI joints, so Dr. Barr again recommended prolo. Discouraged, I agreed. Wow, after 3 sessions I am pain-free with little aches due to weather changes. First time in years, I’m pain free and happy.
