How back pain appears

Back pain occurs and is maintained by a neurological mechanism:

1. Activate a specific nerve fibers, known as Ad and C, or "sensitive to capsaicin" or "nerve pain" -.

2. Their activation triggers cause inflammation and pain and muscle spasm.

3. It is a vicious circle of inflammation and muscle contracture remain activated pain nerves.

4. There are scientific studies showing that if the activation of Ad-C fibers lasts long enough, are triggered biochemical mechanisms that may perpetuate their activation indefinitely. In this situation, the pain persists even disappear because originally triggered it.

The neurological mechanism that causes pain, inflammation and muscle contracture:

1. It can be triggered by any structural damage. For example, when a herniated disk nerves are activated are pain in the outer layers of the disk to come into contact with substances that are inside. In this case, an MRI scan would see the break of the fibrous and clarify the cause of pain.

2. But can also be triggered without structural damage. For example, maintaining a poor posture can overload a muscle group and cause contracture and exciting the nerves that innervate pain. If the patient's musculature is inadequate or asymmetric, the overhead can be sustained for long or repeated periodically. In this case, no radiographic examination would see the injury causing the pain.
