Hello rreihart,

Welcome to the NeuroTalk support groups.

As well as posting here regarding your head injury, I just wanted to tell you that there is also a
CSF Leak Forum
here and it may be worth posting your concerns about the potential leak over there as well as here.

There's also a
Forum Search Feature

There are also many other posts on this TBI/PCS forum regarding CFS leak so it's worth checking those out if you want.
