I feel it everywhere once in a while, it's usually in a fixed spot. The sensation comes and goes but is most prominent when laying down. It occurs in the belly up to pectoral area, the ears, the temple, annnd I think that is all..
It's highly annoying feeling/sensing the beat because it makes it terribly difficult to entertain focused breathing, do yoga, lie down, have the head on its side, and lay on firm surfaces (as firm surfaces seem to help focus and re-vertebrate the beating sensation).
this is strange, this very thing has been bothering me since the beginning of the year. Whenever I stand up from a sitting position, I feel pressure in my head, and when I lie down, my pulse does seem to beat very strongly.
