Frequent Concussions--Impact on syrinx?

[Keigwyn]

So, I've just gotten my second concussion since my surgery two years ago...I seem to get them pretty easily now post-op (I never had one pre-op). My CT scans show no bleeds, but I'm concered that the concussions may have impacted my CSF pressure and syrinx. I'm in the middle of a battle with my neurologist to get a CINE MRI out of network, so I don't exactly have good care right now and he's pretty much written off my concussions as irrelevant (he refuses to order another regular MRI).

Does anyone know about the possible effects of concussions on ACM/SM? Or am I just paranoid?;)

Thanks-
