This is just a note to let those of you suffering from Post Concussion Syndrome that there is some real expectation of getting better. I can't comment on your specific cases or your likely outcome, but I can describe mine which hopefully will allow you to apply to your situation as may be appropriate.

In June of 2010, I was wakeboarding behind my brother's boat. I am an active person - male, was 40 yrs old at the time, and an experienced wakeboarder. Was also in good physical condition. I normally ride behind my boat, so I wasn't used to the new boat, wake conditions, etc. In any event, I caught an edge and took a major face slap to the left side of my head. I was wearing a helmet with earguards at them time. I didn't lose consciousness, but knew it was a major hit, saw stars, and had to take a break. My neck felt immediately sore (which is unusual for a wakeboard whiplash, in which soreness usually doesn't show up until some time later). Felt a bit better afterwards, and actually rode a bit more that same evening.

The following week, I only had neck pain which was gradually getting better. The next week, I felt good enough to go wakeboarding again (on my boat) and had a fine day with no falls or anything unusual. However, the next morning, when I awoke, I had spinning vertigo (the room spinning, not me). The next several days followed with increasing neck pain, dizziness, brain fog and general malaise. This went on for weeks.

I was confused because I wasn't sure if the fall was causing my dizziness or the boating outing the week later (boats can sometime cause dizziness just from the rocking of the boat, which can last for a LONG time). It was strange because after the fall I was getting better, but after the boat ride the next week, the next day I got much worse.

Anyway to make a long story short, I went to an ENT doctor for the dizziness and an orthopaedic for the neck. X-rays, MRIs showed everything normal. ENT wasn't sure about an inner ear problem (head trauma can shake things loose in there). Dizziness and brain fog continued, but at least I was still able to work, but not do much else. Sleeping was sometimes difficult.

My condition lasted 10 months before I got better, which now is completely gone.

I self-diagnose myself with having a serious case of whiplash and a concussion. The dizziness and brain fog were a result of the concussion.

There are a few things I did that I am sure improved my condition and allowed me to cope:

1. Rest the first 3-4 weeks. So important. Give the body time to heal in the initial stages.
2. Prayer: why leave your brain's health to anyone else?
3. Exercises: The ENT gave me some motion exercises for the dizziness that I did religiously 2x day for months. I truly believe these helped. They actually make you MORE dizzy when you're doing them, but when you stop the baseline level of dizziness diminished over time.
4. Study: I spent hours on the internet researching brain injury, concussion, dizziness and whiplash. In my case this was a mistake. Prior to getting professional help, there's so much information out there it's impossible to know what your case is or what is causing it. I causes your mind to wander and assume the worst cases. If I had it to do again, I would go to my doctor first to get a diagnosis, and then target your study around that. No need to worry about a life or death aneurysm when a concussion is all that you have.
4. Believing my Doctor - My ortho was a professional, but his bedside manner was horrific. He kept telling me, "these things usually get better with time". As the months wore on, I didn't believe him. After 6 months, I didn't believe a word he was telling me. But he was right. I did get better. After 10 months. You have to remember, you have only one data point (your own), while your doctor has 100's or more based on his experience. I would qualify this point by making sure your doctor is as good as you can possibly access or afford. If you're not sure, a 2nd opinion is warranted.
5. Tests: I insisted on an X-ray, MRI, or CT scan as appropriate. It's likely they won't show anything, but in my case, the peace of mind in KNOWING there's not major structural damage was worth it, especially if the condition lasts for a long time.

I did wakeboard again, in time for the following summer. Almost as good as before, but with a sincere respect for the fragility of my body.

I am not a doctor or in the business of giving medical advice, just an active guy who's had a lot of injuries, and this one seemed like it might help out some others with a similar situation.
