I was in severe pain walking or standing. Dr. Cammisa fused my L4 and L5 with disc replacement. Within 10 days I was back to walking 10,000 steps a day! In 6 months I was climbing hills in northern Pakistan. I just climbed up a steep incline in Venezuela to see Angel Falls. Dr. Cammisa is a magician and gave me back my life of travel and adventure. I’m 73 and living life to the max thanks to Dr. Cammisa and the HSS team!
