A small tip.........buy some licorice sticks and keep one between the teeth [like a cigarette]........

Some people suffer from TMJ.

[to read in short about this condition open the link :

http://www.mayoclinic.com/health/tmj-disorders/DS00355 ]

Sometimes the treatment can be remarkable effective:[but totally unknown in Western-conventional medicine]

an acupuncture needle below the knee in the acupuncture point St 36 [one or both sides]

We have seen people improving on the spot and sometimes-if necessary- a repeated needle can keep them free of the symptoms of TMJ.

Tip: if you have problems with TMJ then buy some licorice sticks and keep one between the teeth [like a cigarette] for some or most of the hours of the day.

This will cause automatically a relaxation of the muscle-spasms of/around the jaw.

If applicable let me know your experience , please.
