Heart beat in the ears
A friend of mine has a weird problem that he often hears hearbeat in his ears. This happens when he puts earphones (the big ones which cover entire ear) and also when he sleeps. Also, when he is exercising in a high intensity, he hears heart beat and he has a sensation of ''stuffed ear'', like you get when water gets stuck in your ears-in that moments he feels like he is breathing through his ears, like air is coming out of them.
It all sounded pretty strange to me and i was curios, is this maybe a part of some sindrome that TCM is aware of?
