Thanks for the info and insight Hockey. I am seeing a doctor on Monday so I will update on how that goes. I agree that MRIs CT scans (and cocky overpaid neurologists) are useless, as they did not show anything from my first injury even though I suffered PCS. Reading a recent post on this forum, just made me realize that my symptoms were triggered after a recent flight. Prior to the flight I felt completely ok. After the flight my PCS kicked in, even worse than my original injury. I am confident that this flight is the cause of my recent suffering. Does this mean I just need to "re-oxgenize" my brain? I also lost alot of blood out of my nose when I got hit. I think this means that the initial blow might not have cause as much harm as I thought, however the altitude and lack of oxygen I experienced really did the damage. Any thoughts on this situation?????
