Brief Simple Relief

I have found a strange maneuver that works in easing my tt, at least for a couple of minutes, so I thought I would share it. If I insert both fingers into my ears, so that they seal the ear canal, then push the fingers up a bit to stretch or enlarge the canal, then push and pull my fingers in and out a little, creating a change in air pressure in the canal, I get a significant reduction of tinnitus for a couple of minutes. I do it occasionally for a about 30 seconds at a time. I have no idea why this helps me.
