Does anyone know about this? I went into cardio/respiratory arrest 3 yrs ago and i wad brain dead for 2 days and in a coma for another 2 weeks. I know my brainstem is compressed and diminished CSF around that area. Im loosing all hope and faith in doctor's, plus they put a VP stunt in, and shouldn't have. A lumbar puncture is supposed to be done lying on your side, rather than sitting up, because sitting up causes falsely elevated pressure. After 9 yrs of having it in and overdraining and causing severe headaches and slit ventricles. Im hoping soon i can find relief before something else happens.
