What is pain? ----does it hurt?

If you have chronic pain, you probably will find little consolation in the fact that the doctors and scientists do not understand very well, and that just popping an aspirin is far from a panacea.
In fact, the experts can not agree that the pain is.
"The pain is complex and challenging, our ability to create a clear definition," said Weiner. "The pain is a lot of sensory neurons and transportation transduction. The pain is a complex mixture of emotions, culture, experience, intellect and emotion."
The American Academy of Pain Medicine is a great help. In its online FAQ under the heading "What is the pain?" You can find this answer: "It is an unpleasant sensation and emotional response to this feeling."
There are several ways to define the pain, however, and since you have is important to consider how to deal with.

One way to share the pain (and perhaps conquer) is the distinction between acute and chronic, says Sally Lawson, a professor of physiology at the University of Bristol in United Kingdom.
The acute pain is what you get when you on duty with a hammer, if you decide to do that. You can also reach, with a twisted knee or a fire.
The chronic pain is long-term, continuous and very frustrating. This can lead to physical injury, viral infections of the nerve, arthritis or damage to the joints and the degeneration of the bones, Lawson wrote.
The scientists also have to distinguish between the pain (with the hammer on the thumb for the detection of this type) and the variety spontaneously, for which there is no obvious cause outside.
A type of chronic pain, called neuropathic, the results are rather nerve damage that the original damage. But recent research by Lawson and a colleague suggests that these pain May, sometimes by the party not damaged nerves.
