I have a pounding in my right ear when I exercise. I notice that it stops when I look up, put pressure on my right artery, or stop exercising. So I know its from increased blood flow thats making the noise because it also goes with my pulse. I had a lump near my right carotid artery at the same time so I thought that might be it. I went to the doctor and they did an ultrasound of only my right carotid artery. It came back fine. Now I am worried. I read that if an artery is narrowing it would make the other local arteries pump more blood thus making that noise. Wouldnt it make sense that if my left carotid artery was narrowing that it would make noise in my right ear? Or are they talking about how if say my right internal artery is narrowing more would flow through the right external artery and not the left side?
Sometimes when I am laying down and I take a really deep breath I can feel blood flow through the back of my head for a few seconds.
I also had a lump near my right artery so I had a CAT scan of my neck. Would they have checked for narrowing arteries or are they just focused on lumps and masses?
I am so nervous I am going to have a stroke or something at any second. My parents say its nothing(I dont blame them because I have major anxiety and have been to many doctors, but none have checked my left carotid artery) . So to put my mind at some ease I tell myself " that if my left artery was seriously blocked that I would be having this thumping noise even without exercise?" Does this sound reasonable or should it only make the noise when exercising?
p.s. Could this be a rare symptom of TMJ? I notice I can hear/feel blood flow on my right carotid artery. If I intentionally make a bruit by putting pressure on my right carotid artery I can feel the vibration in my ear. Also If while I am exercising and I am hearing this pounding heartbeat if I push my jaw forward it stops
