Scott Metzger, MD, SEM Pain Consulting, discusses the types of pain issues his specialty deals with, especially neuropathic pain (otherwise known as nerve pain).

Neuropathic pain is a type of chronic pain that occurs when nerves in the central nervous system become injured or damaged. If you or someone you care about has nerve pain, you know that it can erode quality of life.

Chronic pain affects an estimated 100 million Americans, or one-third of the U.S. population. Approximately 25 million people experience moderate to severe chronic pain with significant pain-related activity limitations and diminished quality of life. In addition to the burden of suffering, pain is the primary reason Americans are on disability.
