Hearing a bruit from your heart is not going to determine what is going on in your head. I would recommend pushing for the imaging.
Thank you,
I have an appointment with a GP on Friday. How do I go about getting this checked out? If the doctor listens to the carotid artery and can't hear the bruit am I to assume that it is not vessel-related? Or do I still push for those tests?
I would recommend having some scans of your head and vessels done, i.e MRI Brain/Head WITH contrast and an MRA OR an MRI Brain/Head WITH contrast and an CTA if possible.
An AVM or aneurysm IS serious. I don't know if you have either, but I would recommend investigating what is the source of your problem. You could also have a problem with your eustachian tubes causing this tinnitus.
