The sensation is as if my head and
neck are throbbing with pressure and
I have to stop walking or slow down and
stop and stand still for a minute or so to make the sensation stop. Sounds are muffled in rhythm with the pulsations and I sometimes feel as if I will pass out, but never have. There is no pain.
I have been checked throughly by my GP, a cardiologist, and an electrophysiologist and none of them could find a cause.
