What Is Involved in Burning Nerve Endings to Relieve Pain?

The process of burning nerve endings to relieve pain includes numbing the affected area with a local anaesthetic, inserting a hollow introducer needle and passing a heating wire through the needle to position the wire near the nerve endings causing chronic pain, explains Spine-health. The tip of the wire or catheter is heated, and as the heat thickens collagen fibers, the nerves are burned.
