I just went thru an inflammation bout and mine are still pounding. 105mm cannon in the right ear. The hydraulic pump on the M-1 tank screaming in the left. FT-4A gas turbine roar at my 6 o’clock. I don’t get a migraine unless I can’t escape. If I can’t get away from the crazy and crawl in my hole for a while the frustration and anxiety start snowballing. It gets FUBAR after that.
Years of gunfire, helecopters, and jet aircraft, throw in some rocket and mortar attacks and voila, lifelong cicadas singing inc my head.
