Hey! I had it for about 4-5 years. It almost completely resolved yeah.
it was just regular neck massages, what I think caused the "fix" was the position and my stretching of the neck. Not sure if I can post links here, otherwise DM and I can show you what I was doing.

She was sitting on the sofa with her knees to the stomach and I was laying on her knees as if they were a head rest, since's she's way shorter than me, I managed to pull my head back above her knees and that's when I swallowed kinda hard whilst my head pulled back and heard a sort of "rubbing" of my crycoid cartilage, and I kinda knew something was fixed because I could feel the relief.

I didn't want to sing victory because a few times I felt I "fixed" it but then it would come back. Now it hasn't come back, at least not that strong, it doesn't bother me anymore **knock on wood**-

Regards,

She had her knees/legs like this on the sofa, and I was resting my back on them, but part of my shoulders/neck was above the knee line so I could tilt it back, that's when I swallowed and felt it crack and it was "fixed".
