I believe I have a possible head tumor. About a year ago I was experiencing buzzing in both of my ears that would only last a seconds. It would happen just a couple times a month. Then the buzzing became longer periods & was happening more often. Then it eventually became a constant buzzing in only my left ear. I have lost most of my hearing in my left ear. This hearing loss has happened within the last 4 months. I also have had my vision in my left eye intercepted by by whatever is causing the buzzing in my left ear. With thin the same 4 months, I can not see very well in the Left eye. It’s very blurry. Even if I put something close to my face, I still can not see things clearly. The buzzing is constantly going on from the time I wake up to the time I go to bed.
