Hi. I'm so glad I found this site. My 15 year old son began having headaches, dizziness and blurred vision over 3 months ago. We have seen multiple Drs and had MRI's and were finally diagnosed with Post Concussion Syndrome just last week. He plays football and apparently had a concussion that we were not aware of during the season. Like I said, it's been 3 months---his grades have gone down drastically and he still has daily headaches, dizziness, blurry vision and is unable to concentrate on his school work. We are glad to finally have a diagnosis and the Dr says he will eventually get better. He is starting vestibular rehab next week. Guess I'm just wondering when "eventually" will be.
