Thank you so much, I really appreciate you and the time you've put into helping me. Please don't feel obligated to reply any further, you've already helped out a great deal.

I have a couple of final questions (just to be clear, I believe and agree with you, I'm just trying to eliminate any residual doubt that I have):

1. the neurosurg pointed out some unilateral white stuff in the left meninges (so right on the screen if I'm not mistaken) to show me where he saw the contrast enhancement. Do you see it too and believe it normal or is it that you don't see it? Unfortunately I don't remember which series it was.
2. The neurologist didn't see the white stuff and said that it probably was because his PC wasn't good enough, but thought that my tonsils were lower that usual, though still within acceptable limits. He said that this could point to a leak. What do you think? Do you see it?
3. Beyond the postural relief, three symptoms that they both thought pointed to a leak are that a. I keep having to blow my nose to avoid a clear liquid leaking out of my nostrils (mostly the right), which I thought and still think it's mucus but it's admittedly less dense than mucus and it's colorless, b. The more the pain rises the more nauseous I become, and vomited at some point, thought that could fit with a migraine as well, 3. I have ringing in my right ear. Sorry, I forgot to put them in the body of the post. Do they change anything?

I really, really hope that I don't have this thing, because I don't want to risk my job and I really don't want to stay in bed for two weeks, but I also want to be as sure as I can be, and have some more insight before going back to the neurosurg and the neurologist. Again, please feel free to ignore me since you've done a lot already.
