I Had A Severe Concussion A Year Ago Followed By

I had a severe concussion a year ago followed by tram attic brain injury 6 months later. I now have a crack in my skull above my right eye. I have constant shooting pains and pressure behind my eye and back of my head usually ending in a black eye. The doctors can not find anything but this is a constant thing occurring at least once a week lasting up to 6 days. Should I be asking the doctors to look for something they are not.
