pain
"I suffer from chronic TMJ, I can't eat apples, steak, most foods that require you to open your mouth, or my jaw will emit a loud bone-breaking-sounding CRACK followed by waves of intense pain WAY beyond the acceptable threshold.  I'm only 33.  An MRI, CTScan, several X-Rays, and worthless visits to "Specialists" did nothing but empty my bank account and receive the news that I have "two displaced discs in my face, and there's nothing we can do." 

I was about to give up then said heck with it and sought out a pain specialist.  She witnessed the horrific noise, saw the X-rays and surgeon notes, and immediately put me on ZoHydro 20mg (twice a day) and thinking my woes were addressed, then they reformulated it and it's like taking aleve."
