Hi Gareth, My husband had a spinal leak back in 1987. A neurosurgeon, Dr. John Raggio from Lake Charles, La is the dr who went in and fixed it. My husband did not have anymore problems with it after that. I believe he is still in practice there. He is a very good dr (he is prob the best or one of the best in that area) but does not have a good bedside manner (kind of gruffy) and also, if you are a smoker, he will not touch you. Good luck on finding a good dr. and God Bless
