I have been experiencing thumping/drum beat as I call it in my left ear...not sure when it started, maybe 6 months ago. It comes and goes, doesn't happen every day. I have had headaches and neck aches and am under stress as well. My ENT doctor checked both ears and said that everything seems normal. It usually only lasts for an hour or so, but tonight it has been going on for hours, even keeping me awake. I tried googling this, but didn't find any answers that made sense...however, I have read some comments regarding magnesium...does this help?
