Pain Slideshow: Causes of Back, Neck, Wrist, and Headache Pain: "- Sent using Google Toolbar"
Seems like just about everything can cause pain if you watch this slide show. Pain is still not completely understood, but what we do know is pain is unique to each individual. Each person experiences pain in their own way.
The nervous system is not largely dedicated to pain. Pain fibers in the nervous system are relatively few and thin. When we experience pain it means that the level of the pain signal is significantly increased versus other nervous system function. Pain simply serves as an alarm that something is wrong, but the alarm does not go off until there is a very large message being sent to the brain. This is the reason that some serious medical conditions which take time to develop lie under the pain radar until the later stages.
