I too had exactly the same constsnt ringing in my left ear.

I could not get to sleep because the noise was so loud and intense.

It reminded me of those spy films where they torture someone playing loud heavy metalcore all day and night.

I had a X-ray, ultra-sound and two Consultants had a look.

Both said that there was nothing wrong with my ear. No ear wax, no damage, no issues at all.

They both mentioned that tense facial and neck muscles may be a cause.

As well as the constant ringing, there is a sound like a central eating system, thumping and groaning away, in both my ears too. I initially thought the thumping and groaning was the Mrs snoring.

I bought some earloops thinking my ears were too sensitive and I was somehow hearing noises from the houses down the road and the motorway traffic 3 miles away. to no avail, even with the earloops blocking all exterior noise, I still had the high pitched and low piched internal noises.

I found a way to reduce the noise.

I was laying in bed one night and I was relaxing my jaw when I noticed that if I opened my mouth and let my jaw hang loose all the noises stopped.

So over a month or so I tried to train my jaw to be less tense and more relaxed.

For me it worked.

it was my jaw.
