Hi, I just had a lumbar puncture and had an opening pressure of 360 mmH2O; I know this is above the healthy pressure, and I trust my physicians to take care of and properly diagnose it, but I was wondering--how rare is it for the CSF pressure to be this high? They reduced me down to 90 mmH2O, so I'm probably in the clear for awhile now, but my mother and I are trying to contextualize it. (The tests haven't come back, but the current hypothesis is probably IIHP)
