Presently, every time I bed over a little too far, or strain too hard, within 5 minutes my forehead tingles and within a half hour I have a severe headache. The
duration and degree of bending over or straining, directly relates to the duration and severity of my headache. This is not a normal headache... It is a strange, throbbing, shooting pain that sometimes travels from behind my eye down the side of my neck with every heartbeat, accompanied by generalized headache on that side of my head.
