Pain is generally an unpleasant feeling in response to an event that either damages or can potentially damage the body’s tissues. There are four main steps in the process of feeling pain: transduction, transmission, perception, and modulation. The nerve cells that detect pain have cell bodies located in the dorsal root ganglia and fibers that transmit these signals to the spinal cord. The process of pain sensation starts when the pain-causing event triggers the endings of appropriate sensory nerve cells. This type of cell converts the event into an electrical signal by transduction. Several different types of nerve fibers carry out the transmission of the electrical signal from the transducing cell to the posterior horn of spinal cord, from there to the brain stem, and then from the brain stem to the various parts of the brain such as the thalamus and the limbic system. In the brain, the pain signals are processed and given context in the process of pain perception. Through modulation, the brain can modify the sending of further nerve impulses by decreasing or increasing the release of neurotransmitters.

About 80 percent of the population suffers from a bout of low back pain at some point in their life. However, some people are at higher risk for chronic and acute back injuries due to their lifestyle. For obvious reasons, athletes are at greater risk of sustaining a lumbar (lower) spine injury due to physical activity. Whether the sport is skiing, basketball, football, ice skating, soccer, running, golf, or tennis, the spine undergoes a lot of stress, absorption of pressure, twisting, turning, and even bodily impact. This strenuous activity puts a strain on the back that can cause injury to even the finest and most fit athletes. Though the entire spine is used when playing sports, it is estimated that 5-10 percent of all athletic injuries are related to the lumbar (lower) spine. Many cases of low back pain in athletes can be traced to a specific event or trauma; others are brought about by repetitive minor injuries that result in microtraumas.
Towels, Stands & Hooks The low back, or lumbar area, serves a number of important functions for the human body. These functions include structural support, movement, and protection of certain body tissues.

Select One About 9 in 10 cases of nerve root back pain are due to a prolapsed disc – often called a slipped disc. (A disc does not actually slip. What happens is that part of the inner softer part of the disc bulges out (prolapses) through a weakness in the outer harder part of the disc. The prolapsed part of the disc can press on a nerve nearby. See separate leaflet called Slipped (Prolapsed) Disc for details.) Other less common conditions can cause pressure on a nerve to cause nerve root pain.
Printers To paraphrase Forrest Gump, lower back pain is like a box of chocolates: You never know what you’re going to get. This kind of pain can be sharp and stabbing, dull and achy, or even radiate into other parts of your body. It can last for a few hours, months, or years. Unfortunately, it also happens to be shockingly common—great when you’re talking about chocolate, not so much when you’re discussing pain.

These exams look for diseases that can cause pain referred to your back. The lowest nerves in your spinal cord serve the sensory area and muscles of the rectum, and damage to these nerves can result in inability to control urination and defecation. Thus, a rectal examination is essential to make sure that you do not have nerve damage in this area of your body.
