Hi, Kimbob, and welcome!
Can you give us a little more information about your pulsating noise --- when did it start, have you had tinnitus or hearing loss in your right ear prior to this occurrence, and do you know of anything that has changed in your life that might have caused it?
Pulsatile tinnitus usually has a vascular cause. If yours doesn't go away after you've given it a reasonable amount of time --- say, maybe two months --- you might want to go to a doctor and have it checked out. I went first to an ENT, and he referred me to a neurotologist. A neurologist might be able to help you, as well. The doctor might order tests for you, such as an MRI or a CT scan.
Please note your symptoms, so that you can discuss them with your doctor if you do decide to make an appointment. I hope you'll keep us posted on how you're doing.
Best wishes,
Karen
