I am curious to learn more about post concussion syndrome. In the past 4-5 years I have had 4 or 5 "mild" concussions and am starting to get worried. I received all of these from sports and have since pulled myself from such dangerous situations but I fear I am still dealing with the after effects of my reckless youth. After my last concussion I had extremely bad vertigo, memory loss, and headaches. They got so bad I had to get a Cat Scan because they thought my brain might be bleeding, thank god it was negative. Well I recently got in a car accident and have no clue if I did hit my head or not. I went to the ER and I was cleared in a few hours. That night I had the worst Vertigo, when I say Vertigo I mean spins and dizziness if I am using this wrong sorry I was told that this was the correct term, which result in my inability to stand, see, and really talk. They wanted me back in the ER asap but I refused because I thought I could just deal. Well it has been two months since the crash and I am still having issues. My balance, which used to be great since I was an athlete all my life, is terrible. I bump into doors, wall, trip constantly, my memory is no where near what it used to be. I have issues remembering simple things like take out the trash to long term things like next Monday go to the Doctors. I still have headaches and all of this scares me. Is there a chance all these concussions have done some serious damage to me? Is there anything I can do? Please help, thanks.
