Blocktrades thank you very much for your advise and much needed vote. Yes I have had a Harrington rod implanted when I was 16 years old. Had a neck opp when I was 43 years old, and now the very lower part of my spine has crumbled and the cushion tissue gone, and the constant pain with almost no support, and no cushion between the vertebra's makes life really tough. Once again thank you for your vote
