Tinnitus is very common, but not well understood. In fact according to Mayo Clinic some forms of tinnitus affects about 1 in 5 people. One of those people is me. In most cases it is not a serious condition just an annoying one with little or no treatment options.
A little history
Back in my teens I had my first tinnitus experience after a night of heavy drinking and a scuba dive the next morning, (not recommended btw) .. I now believe my then undiagnosed AVM was irritated from a combination of my increased blood pressure from the alcohol and the water pressure of the dive. It was a sudden onset of symptoms that cut my dive short and lasted 6 months with no diagnosis. My family thought I was going crazy and at times I thought I was. You can read the full story in my very first post here if you have time for my jibber jabba.
Anyway's to cut a long story short, I was not going crazy, my symptoms came back 13 yrs later in 2010 after a new workout routine were I pushed myself too hard which I believe once again irritated my AMV and lead me to my AVM diagnosis.
What is Tinnitus
I have noticed many of us AVM survivors have mentioned they have experienced one of the symptoms below and thought I would share my findings now that I have a better understanding of the once unexplained high pitched screeching sound I have in my head.

Hear is a video on Tinnitus with the exact sound I can hear when I'm in a quiet room
I can also hear the blood swooshing and swirling around my blood vessels in my head each night when I'm laying in bed along with that consent whistle screech sound. Some people have it worse and louder than others, some people have a different sound they can hear. I can live with mine it's not so loud and I'm kind of used to it now. Sometimes I don't hear it unless I concentrate to see if it is still there but it always is.
There are a few different types of tinnitus including one called Pulsatile tinnitus. This is a rare type of tinnitus that sounds like a rhythmic pulsing in the ear, often in time with your heartbeat. Doctors can sometimes hear it by pressing a stethoscope against your neck or by placing a tiny microphone inside the ear canal.
Pulsatile tinnitus is most often caused by problems with blood flow in the head or neck such as AVM's. The sound some may hear can be caused by kinking of arteries/vessels, or a buildup of cholesterol in arteries/vessels causing blood flow to become more forceful and sometimes more turbulent, making it easier for your ear to detect the beats. However it has also been known to be caused by brain tumors and other abnormalities in brain structure.
I hope I have answered some of these unexplained noises some of us can hear. If you can hear these strange noises and your a member of this group, your AVM is likely to be the cause. Make sure your tell your doctor so they can review your MRI's and rule out other possible causes.
