BILL H. MCCARBERG, MD: Unfortunately, we don’t have enough pain experts to treat chronic pain, so most of the burden for treatment falls on the primary care provider -- the internist, the family medicine doctor, the pediatrician, the OB/GYN doctor.

ANNOUNCER: Chronic pain can also prove difficult to diagnose.
RUSSELL PORTENOY, MD: Pain is inherently subjective and what we mean by that is there is no test that can determine whether or not a person's experiencing pain. There is no laboratory test, there's no X-ray, there is no test that can tell a doctor or -- or any other person that another human being has pain. The only way that we can tell if a person has pain is that they report it verbally or they show it in the way they move.
ANNOUNCER: There are different types of medications used to treat chronic pain. A group of medications called non-steroidal anti-inflammatory drugs, or NSAIDs, provide pain relief by reducing swelling and inflammation.
