chronic pain
"I was diagnosed with degenerative disk disease and osteoarthritis last year, not so bad if you're 75 but I'm 26.  I've had symptoms of this since about 14 or 15.  After 10  years my doctor finally believed me and accepted the fact that I was in real pain (this is finally after 2 well known orthopedic surgeons discussed their diagnoses with him).  He gave me Norco 7.5's, which didn't do much but introduce my liver to a lot of acetaminophen.  He then added fentanyl 50mcg/hr patch 1 every 72 hrs."
