Slow Pain, or Chronic Pain Travels on Unmeylinated Nerve Fibers

Chronic Pain is communicated to the brain much more slowly than acute pain. The nerve fibers that chronic pain messages travel on are not myelinated. These types of nerve fibers are also thinner than those that deliver acute pain signals. Because of this, the chronic pain nerve fibers deliver a different type of pain. They deliver dull, throbbing, continuous pain. This type of pain is probably very familiar to those with chronic pain conditions, and is in contrast to the intense feeling of acute pain in localized areas.
