What ended up happening is my neurosurgeon, Dr. Alden, drained the pseudomeningocele and wrapped a very tight pressure dressing on it, in the hope that it would either heal itself, or stay manageable until I could have surgery.
That's most of the fluid from the first time they drained it.
Thats all the fluid from the second time they drained it: about a week later.
Again, I know this isn't a ton of information, I wrote this post on my phone as well. I've just been having really bad headaches because of this whole thing, and it's much easier to just grab my phone while I'm laying down and post something small. Also, as soon as I feel better, I'll update this and the previous post with more information and more about my actual experience.
