Recently, I've had random times where I'll feel my pulse in my left ear. It came one day and was gone the next. Today it came back. I was lifting sheet rock, so I don't know if it has something to do with more blood pumping in head (and ear), or I'm thinking it's anxiety - as I know anxiety can cause multiple things.
It does not hurt, it's just annoying. It's not constant. It comes and goes.
I've also had this happen in other parts of the body (legs, arms, etc...).
Can anyone explain why this happens, and what I can do about it?
