Hi...many with a syrinx...also known as syringomyelia can have a related condition known as chiari malformation....
A syrinx can form as a congenital condition or it can be acquired from an injury.
First u need to know which u have and if u have related conditions.....most times a obstruction of CSF flow will cause the formation of a syrinx...and depending on the location and size, the type of symptoms u may encounter...and I know u will encounter drs that feel u should feel nothing at all....
I do have in my journal, an article on shunts for syrinx's....u may want to take a look, but drs that do treat chiari also treat syringomyelia...so u may want to try there.
We also have a forum for chiari and we so have others with syrinx's as members-
