got my first concussion at 5, knocked out cold for 4 hours. I have had at least ten other concussions in my lifetime. some were while playing sports, but most were while working construction. I suffer from Migraines, and at 45 my wife kids have told me I am showing signs of dimensia...don't know how it's related but after all those lumps I guess anything is possible. I recently had cervical surgery which is most likely connected with my multiple head injuries.
