I also have had a low frequency hum for 2 years now. It sounds exactly like there´s a faint sound of a car engine somewhere outside near my house. The sound stops when I shake my head, and returns in a second when I stop. The hum also goes away or the volume goes down to minimum after a night out drinking alcohol. So basically when I am hungover. Then it slowly starts again after 1 or 2 days. Crazy?I've posted this on many other threads, but I also have a loud low-frequency hum. It started from out of the blue in the Summer of 1996. I also have a high-pitched hissing that started a few months earlier, but that rarely bothers me. The humming has gotten so bad over the years that I've considered suicide.
When it first began, I had every medical test known to man performed (MRI's, hearing exams, dental, etc.). I even went to an orthodontist who stuck his fingers in my mouth and squeezed various parts of my soft palate while asking, "Do you still hear the hum?" (I did). But of course, no one could find any abnormalities. In 1999, I reluctantly got on an antidepressant (Effexor XR) as I couldn't cope anymore. Within a few weeks, the humming disappeared. I assumed it was all psychosomatic and not physical. But the silence only lasted about a year before the hum returned one morning. I tried other ADs, but none worked. I eventually got on Lexapro and stayed on that one for almost 15 years
Up until March 27 of 2022, I had been hum-free for nearly four years. But then it returned and sent me into absolute depression hell. As I write this, I've been on a newer AD (Pristiq) for about a month, but I've felt no changes.
I don't grind my teeth, so it's unlikely a mouth guard would be beneficial.
My hum also stops when I shake my head in a sideways motion. Sticking my fingers in my ears or cupping my palm over them creates the seashell effect. But when I remove my fingers, the humming is even louder.
The biggest mystery for me (in addition to what's causing it) is why it will go away for years and then return for no apparent reason. I can have a full life when it's gone, but when it comes back, everything changes. I feel vulnerable, trapped, and full of dread. Trying to sleep at night is nearly impossible. I can also FEEL the hum in addition to hearing it. It's a horrible vibration, the kind you feel when riding on a prop plane.
I suppose it's similar to people who have cancer and manage to beat it after chemo and other treatments - there's always the fear that it will return. With tinnitus, there is no approved treatment. That's where part of the helpless feelings come into play.
When the hum started I had a lot of neck problems from working with computer along with tension headaches. I got Amitriptyline medication but it made the hum very loud and I stopped taking it. I also have numbness in forehead and face from time to time and a neurologist thought it is tension headaches (neck tension). I have done everything I can from exercising 4 times a week to going to massage countless of times in a couple of years. And yet this crazy hum continues, sometimes louder, sometimes quieter. Starting to think it is from bite and the jaw muscles because I am running out of ideas...
