Hi: One month after a break through Covid infection, my left ear woke me with a loud tone, following with pulsatile tinnitus. Prior I had a few low heartbeats after lying down, but they would fade away. Have had all three scans with all normal results. My right side had a little sound but it fluctuates with the heartbeat. When you do physical activity it gets louder or even a bad dream when your heart pounds. I’m planning on having my scans re-read at Mayo. My position or time of day doesn’t change it. It’s been almost a year. Any thoughts?
