I am doubtful you can answer my questions but I will give it a shot.

My healthy Dad 74 yrs old has been bed ridden for nearly 2 yrs, from head pain. Not a headache, not a migraine, he describes it as a creepy crawly pain. Rates his pain between a 1-10 dayly he is at a 5 when he can function. If he reaches a 6 or above he is straight out in bed. Sometimes barely able to go to the bathroom. WE have been to 20 Drs, with all kinds of tests , noone can find what is wrong with him. He renetly has been seeing a botox/plastic surgeon specialist who has preformed two surgieries both unsuccesful.
