TMJ (tempora-mandibular-joint disorder) - here's  what works for me:

- night guard from dentist (plastic thingy that you wear at night in your mouth to prevent grinding your teeth)

- hot compresses over the painful area

- stop using cell phone - it seems to really aggravate symptoms,  creating earaches and TMJ.  I've used a headset succesfully too,  although an earbud probably just channels the radiation into the  ear (not good).

- passionflower tea for the pain.  you can buy  it in the health food store, and I'd use 2 teabags to make a strong  brew and drink 2 or 3 cups.  it's non-addictive, and considered  safe for long-term use as a sedative, painkiller, muscle relaxer...
