My Husband Has Arachnoditis And Over The Last Couple Of

My husband has arachnoditis and over the last couple of months he has started to feel faint and passes out. He had a spinal fluid leak from April of 2015 to September 2015. After the leak was fixed he started having terrible nerve pain which is when we found out he has crumpling of the nerves. The passing out is very concerning and we wonder if the spinal leak could have caused some other problem.
