Pain is a normal sensation in the nervous system that begins to alert you to any possible injury and your care. Severe pain is usually caused by a sudden illness, fire, or tissue injury. The cause of severe pain is often diagnosed and treated and the pain is confined to a period of time or stiffness.
Chronic pain never ends – it lasts longer than chronic pain and is resistant to most medical treatments. Signs of pain persist for weeks, months, and years after the initial traumatic accident. Pain can be due to an existing cause such as cancer, ear infection, etc. It is a different matter that people have chronic pain even in the absence of any previous injury or physical harm. Chronic pain is commonly associated with paralysis.
Pain is a complex definition that varies from person to person, even among those with identifiable injury or illness. People with paralysis usually have neurogenic pain (this results from injury to the nerves or spinal cord in the body or the brain itself). Treatment of chronic pain includes therapy, acupuncture, local electrical stimulation or induction, brain stimulation, and surgery. Psychotherapy, relaxation and medication therapies, biofeedback, and behavior modification can also be adopted.
