Is the thump in the same place as where you check for your pulse? The reason I ask is because I have some weird pulsing sensations on the right side of my throat, down lower on my carotid artery. I can even see my throat moving. It only happens sometimes, and generally my pulse is going faster than normal at the same time. I'm thinking mine might be related to my pvcs and nsvt. Do you have pvcs?
It does seem to be lower down than where I take my pulse. I don't recall the cardiologist saying anything about PVCs, but he might have. I know there was something not totally normal on my EKG, but it didn't wind up being anything bad. I do suffer from anxiety/panic attacks. The thumping/jumping could be related to anxiety maybe, because I do have alot of "under the surface" anxiety right now.
There is a major muscle that runs almost right over your carotid artery on both sides of your neck. It could just be a slightly spastic muscle twitch.
That could be. I do get a lot of twitches in various muscles. Thanks for the response.
OK, I know I'm reviving an old thread, but does anyone know what that muscle is?
