Sometimes a whooshing sound or a lot rumble sounds that pulsates. I can hear it all day and over conversations I have with people. It might have sounded that it was external to me but no one else ever heard it. So I put it down to grief and stress. I had so many checks by specialists and I get an MRI done every so often because when I was getting checked out they found an arachnoid cyst on the right side. However, specialists have said that it is unlikely to be the source of the pulsating.
