Pain Management

kristynmarie.com Pain is the sensation or feeling resulting from or accompanying some injury, derangement, overstrain or obstruction of the physical powers. It is the means by which the Peripheral Nervous System (PNS) warns the Central Nervous System (CNS) of injury or potential injury to the body. A pain signal is transmitted to the CNS by special PNS nerve cells which are distributed throughout the body and respond to different stimuli depending on their location.
Pain can be sharp or dull, intermittent or constant, or throbbing or steady. It can be very difficult to describe sometimes and may be felt at a single site or over a large area. The range of pain intensity can vary from minor to intolerable.
Pain felt in one area does not necessarily provide an accurate representation of the location of the existing problem. It is possible that pain can be referred from another area. This is so because signals from several areas of the body often travel through the same nerve pathways going to the spinal cord and brain.
The evaluation of pain is done by considering the history and characteristics of the pain. The severity can be determined by describing it as mild, moderate, severe or excruciating or using a scale of 0 to 10 to describe it. No laboratory test can document the presence or severity of pain.
