Hi, I am 14 years old, now why I am on your forum and asking you this question is that I am really very concerned about my dad who is 35 years old. Last night I heard him talking to mom about some complications that he has been going through. He was talking about Dural sac and the pressure on the Dural sac that was troubling him, I really don’t know what is Dural sac and what are the problems that it can create?
