I have PCS and I can't drive right now because of a seizure disorder, so I have been biking to work when the weather permits. Last week, I hit a pothole (didn't fall off bike) and I was wearing a helmet. When I got home, I noticed that I had a headache. The pain got worse as the night went on. The next day I had to stay home from work because the headache was so severe. Today was the first day back on my bike and my head is hurting again. I am getting tired of walking everywhere so thought I would try it again. Now I'm thinking biking isn't the answer. Any other people suffering from PCS and enjoy bike riding?
