my neuro is concerned that i have another csf leak. which from what he is telling me the symptoms are i would have to agree. the blurred vision, double vision, ringing in the ears, crushing head pain (if in an upright position for 20 min or longer), ears feel like they are full of fluid, balance is off...ect. the one thing that is really throwing me off is if my spinal fluid is too low is it normal to get confused and zone out? i can be sitting concentrating on what my 4 year old is doing and saying to me and all of a sudden she is hitting me and yelling at me and i don't remember what was happening or even remember zoning out. the other issue i have been having and no one has listened to so i am assuming is not a big deal is when i have been up for too long i will feel like someone is sitting on my chest and that my lungs just don't want to inflate it is sore like it is being crushed. (it feels almost like once in a while i will forget to take a breath and i have to concentrate really really hard to breathe and take a deep breath.) my stats are always normal as far as o2 97 to 100, but i will still feel like i can't breathe. is this normal?
