I wonder if anyone can identify the cause of a noise coming from the brain that only that person can hear. It is like a 'hum'. The doc suggested cardiovascular tests. He believes it may a circulation problem.

Hi,
I am having the same problem...still waiting on my doc to schedule my appt. Its a very noisy buzz sound. I have noticed that it happens more when Im laying my head on its side. So I m thinking maybe an ear thing. I am worried about tinnitus though because I also have simliar symptoms of that. Have you ever had an MRI. They said I had a benign pineal cyst. That was 2 years ago. Good Luck and let us know what you find out.
