Pulsatile tinnutus. It sounds like you may have pulsatile tinnutus. This could be related to eustachian tube swelling (the tube that leads from the middle ear to the back of the nose.) a rare cause of this can be a vascular tumor in the middle ear, so you should have this checked. Work-up may include a hearing test, an exam of your ear using a microscope, and possibly an mri/mra scan.
