Hi everyone... I was wondering, is it possible for brain cells to start functioning differently out of nowhere? This is definitely not normal. It all startd when I got sick in the hospital and my blood gases went all out of whack, as soon as I got discharged I have been feeling this terrible sensation of claustrophobia that stays with me every second of every day. I've had an eeg, mri, abr, and a lumbar puncture and all the tests were negative... I feel like my head is trapped in a box all the time and my vision is different. I still have perfect vision but if I look at something that is far away it makes me dizzy and I get this weird "cotton like" sensation in my head. Its been like this everyday for almost a year. Could this maybe be something that my brain cells are doing or something? Could there be any chance of me taking some type of drug or anything so I can get better?? If anyone has any ideas deffinitely let me know. Thanx.
