On Monday September 4th, I was in the bathroom, groggy and my MERRF caused me to fall without putting my hands down. I slammed my head on the floor of my bathroom. Fortunately, I didn't hit my eye or head on the toilet bowl, sink or towel rack. As I rose to my feet, and looked into the mirror, I noticed a gash on my upper left side of my head. So, I called my father and began to ice it. After icing and applying a cloth to the wound, the bleeding did not stop. Therefore, I called my father back and he drove me to the ER because I didn't know if I had a concussion or not. Though I needed four stitches, I didn't have a concussion. And, the ER said I did not have any restrictions for driving or otherwise. I am a very positive and outgoing person, yet I often wonder how much brain damage do I have. Over time, I have suffered a few massive head injuries, which were diagnosed as concussions. Do you have something that you think about often?
