Hello, Yesterday I woke up and had this noise in my right ear. I realized it was my heart beat. Also had dizzyness/vertigo which was getting worse again with an incident last week. I went to a clinic and they did an ekg and said I'm not having a stroke. I have type 1 diabetes and hashimotos. I'm going to an ent on thursday. Do you think this could be serious? It seems to get worse at times and I can't hear it at all when I'm talking or there is another noise usually but sometimes it gets louder. I just wonder what is causing this? I'm scared. and it's driving me bonkers when things are quiet. Will supplements help? I had a brain mri and video nystagmography last year. The mri was normal. Could it still be some vascular cause which didn't show up? I also had a migraine on the weekend and the doc said my sinuses were very swollen but my ears look normal. She said the migraine and sinuses could cause this too and it's likely my carotid artery that I'm hearing. I also had some fluid in that ear and jumped up and down to get it out, could that cause this?
