I have had ringing in my ears for a month. I had a CT, chest X-ray, and blood work done. I went to the ENT he told me it was not my ears. No fluid, no infections are present, and sinuses are good. He told me it could be an aneurysm tumor or pressure in the brain. CT showed no signs. What could be the cause? I also get dizzy at times but not always. Someone said it could be a sign of a heart attack. I was taking cholesterol medicine before this issue but stopped that, and also, my primary doctor. gave me Flonase with steroids that did not work either. This is driving me crazy. They said to go to the neurologist.
