What could a swishing noise be?

I've had a problem with tinnitus (ringing in the ears) for many years and one of the interesting things I read about it was that some people hear swishing noises because the carotid artery is so close to the inner ear. What they're hearing is the blood rushing through the artery. Everyone's anatomy is a little different (as to placement of vessels, etc.) so in some people that artery lies closer to the inner ear than other individuals. If you've had everything checked out and there is no other abnormality, count yourself lucky in only hearing the swishing occasionally. My ringing is constant in both ears---like a high pitched whine. I pretty much try to ignore it and stay away from caffeine and salt which can increase the volume. Hope this helps!

oh lord i have the same thing and it is so annoying im so sick of it i spoke to a ear throat and nose md and he said that it could be blood circulating a vessels that is too close to my ear or even an aneurysm so it kinda scary im going to get an mri you should do that if haven't already

im not sure maybye your just like me... sometimes i hear screaming and screaming and screaming and screaming in my head but not scared screaming its the kind of screaming you hear when someone is being tortured evil and sadistically.

but it goes away and then comes back maybye a day later (sometimes 2-4 days) hmm... maybye ill post a question asking what my problem is.

maybe there's a bug in your ear? There was an ant in my ear once and i heard a swishy noise when it moved.

What you are "hearing" is the blood circulating within your ear.
