As you have already read, i suffered a grade 1 concussion on Sept 13. Today is December 4th and i'm still sufferring side effects. Im working, moderately riding, but face tunnel vision and nausea when lying on my right side. I have been diagnosed with " Post Concussion Disorder." Basically, my brain is taking its time healing and will let me know when its safe for me to ride again. Its been a long emotional struggle, but with proper medical help and medications, I am dealing with it. I feel so helpless, not just being able to get on my bike, and ride. I have to think everything I do, through first. I like eating with a fork, rather than a straw. Im still torn on what brand of helmet to get, but rest assured it will be snell/dot approved. peace.
