Weird wooshing in my ear?

That isn’t high blood pressure. It’s pulsatile tinnitus, which is related to blood flow, not blood pressure. You’re essentially hearing your own blood moving. It can also be caused or worsened by TMJ.

@ashlynnmae

COULD it be blood pressure?

@ehdog

I wouldn’t say that. Even if blood pressure plays a role, people with normal or well controlled BP experience this all the time. It isn’t a sign of uncontrolled hypertension or dangerously high blood pressure.

@ashlynnmae

So it could play a role?

@ehdog

I already explained that it isn’t a sign of high blood pressure. It’s not a warning sign.

@ashlynnmae

I'm confused. You said even if it plays a role.

@ehdog

Yes, even if it did, not that it actually does.

@ashlynnmae

It doesn’t indicate high blood pressure at all. Plain and simple, you’re just hearing your own blood flow.

When blood is forced to squeeze through a stenosed passage, it can make a whooshing noise as well. This could also be a sign (could be, not 'is'...) that your carotid artery is getting closed off due to plaque. A Doppler Ultrasound can show if this is the case.

I think Oranges is spot on identifying your condition. Initially, about 3 years ago I would get out of bed at night searching for running water. Finally I figured out the noise was in my head, coming from my left ear and it was highlighted by my heart beat. I do have high blood pressure which I take medicine for by if it is elevated the running water sound is louder and the noise beats in time with my heart beat. It's a good warning to take an extra bp pill.
Pulsatile Tinnitus can have various causes. On the internet several causes are mentioned. It can be a brain bleed or tumor but I had a brain scan and am fine.
But in my case I think it may be resulting from 2 other issues. One could be from an automobile accident resulting in 3 tilted discs in in my neck. I hit a windshield at age 16 and now in my late 70's the resulting traumatic arthritis in my neck is restricting movement or it could be the severe earaches as a child for which my ear drums be lanced to release pressure.
