I'm just curious, does anyone play (or has anyone played) a wind instrument in the past? Either professionally or recreationally? It seems that the clarinet players I know have all had to deal with tmj dysfunction. When I quit playing in March the pain was unreal (in my face, pulling down into my neck and shoulder). My emboucher had deteriorated to the point where I couldn't play any longer than 10 minutes. Unfortunately, that last time was during a concert, and I had to keep going.
The one girl I spoke to said that switching to the bass helped her symptoms, but apparently, it didn't do the trick for me.
Maybe tmj is one of the hazzards of being a musician...like tennis elbow.
