On December 8'th, 2011, I had a major collision playing ice hockey. This resulted in light headedness, headaches and irritability. The symptoms lasted for almost exactly 2 weeks and then went away 100%. I took some more time off over the holidays and played ice hockey again on January 11'th, 2012. I played a very careful game and took no hits or even bumps. However, the light headed feeling returned by the late third period and has not gone away since.

I've seen a neurologist, had XRAYS and an MRI. No issues found. I've been checked for hypoglycemia. My blood sugar is great. I took a stress test today on my heart. Nothing. I'm in flawless health.

Over the last week I've been feeling quite a bit better. But after today's stress test ... which is the most vigorous activity I've had since January 11'th, I feel light headed again... pretty bad.

What is going on? Why does physical exertion cause this? Is this normal with concussions? I'm not having another concussion each time I exercise am I?

One other consideration. In late November... before the concussion... I had a sudden and scary dizzy spell. Room spinning, had to hold myself up from falling dizzy. I went and saw my PCP for this and he said it might be a slight inner ear fluid imbalance and it should go away in 24 hours. It did go away. I never thought about it again. In hindsight now.... I wonder if it's somehow related. Probably not, but thought it would be worth mentioning.

Thanks,
Todd
