Yesterday morning I was awoken by a whooshing heartbeat sound in my left ear.

I immediately thought high blood pressure but mine was 119\66 so totally normal.

It kept me up last night because it was so annoying and it's still doing it today.

I have a doctors appointment tomorrow and logically I know it's probably an infection, but when I google whooshing heartbeat in ear some pretty scary stuff comes up.

Anyone have this before? What were your experiences?
