Hi all about three months ago I was at the hostpital to get surgery done on my tethered cord. I am seeing Dr. Fraser Henderson and we are trying to rule things out (I do not have a chiari malformation). Anyway, while they did a standard procedure spinal tap my spinal pressure came back double as normal! He immediatly put a LP shunt in after the first surgery. Now, three months later he is baffled how it didn't help or affect me at all. He wants to get a test done to see if it is working but I am still in the dark as what all this means. He diagnosed it as psuedotumor cerebri but i think there is a cause and it isn't just spontaneous after all the other stuff i have got going on. I feel like I actually don't have ENOUGH spinal fluid because I can't shake my head, go over speed bumps, and bend over without it hurting so much(feels like lack of shock absorbtion). So could someone explain what this all means and what it is related to? I think something is blocking it or something for pressure to build up in the spinal canal BTW I have POTS, an unknown connective tissue disorder and a retroflexed odontoid
