One of the things I find most interesting about ANs is that there seems to be no correlation between tumor size and number and severity of symptoms.
There are lots of cases on the Forum of people with small ANs that caused big and numerous symptoms and on the flip size there are people with large ANs that caused small and few symptoms. There seems to be no rhyme or reason involved.
And like you, I find it interesting how we all have unique AN journeys. I'm SSD, but don't have headaches (despite the fact that most will say retrosigmoid patients generally have them), didn't have a CSF leak, and experienced very slight facial paralysis (again something that seems contrary to the retrosigmoid approach).
I also find it very interesting the things those of us who had surgery experience post op. I had massive nausea, double-vision, and no pain; yet others I know had no nausea or double-vision whatsoever and had pain.
Just goes to show ya, like your subject line says, we're similar but different.
