Back of skull pressure, im not to sure if i have been making a bad mistake on resting my head on the back of a steel bar headboard sligtly when im in bed watching tv or on the computer, but when i sit up after a while of sitting with my head on the back of the headboard my brain i can't put it to prespective really but my bain slowers in a sence, and i guesse you could say foggy, its rather hard for me to explain but im unsure if its pressure on the back of my skull and could the back of the skull be very sencitive towards this and is easily effected when this occours? As could the brain be effected or damaged by this simple process please somone provide me with an aswer to my on going experience. thanks.
