Last night on Nightline they had a medical mysteries segment. One of the stories was about a man whose skull was too small for his brain and his brain was actually seeping down out of the bottom of the skull and causing extreme symptoms all throughout his life because of where it was pressing on the spinal chord and impeding the nerves and all. He had had headaches, couldn't sneeze without extreme pain, etc all his life. They cut his skull opened and created more room at the bottom and it was a miracle, all of the other symptoms stopped, even his allergies!
I sure hope this little guy is alright and just had a crick!
