There are several pain management techniques available to make the person free from pain. Some of them are intake of drugs, psychological treatment, exercise methods, meditation methods and nerve block method. If the pain is acute in nature then treatment such as consumption of drugs and exercise will do the work but if the pain has become chronic in nature then most of the above mentioned treatment will not work and the only one will work is nerve block method.

We feel pain because the signals from the paining nerves are reaching to the brain. So in this technique the signals from the paining nerve are blocked so that signal will not reach the brain. This is done by injecting chemicals such as phenol and alcohol in the area around the nerve or in the spine. This treatment will give relief from pain only for 6 to 12 months and has to be repeated again after this time. Nerve block is mainly used for chronic type of pain.

There are several uses of nerve block: it can be used as anesthesia for small operations, to find out the source of pain in the body. Besides advantages of the nerve block, it is not risk free.
