Pain management
Pain is an unpleasant sensation in animals that is caused by actual or perceived injury to body tissues and produces physical and emotional reactions. Presumably, pain sensation has evolved to protect our bodies from harm by causing us to perform certain actions and avoid others. Pain might be called a protector, a predictor, or simply a hassle. In this article, I will discuss some basic concepts of pain.
We all experience pain to greater or lesser degrees at various points of our lives. It is said that pain is the most common reason patients seek medical attention. But, each of us perceives a given pain stimulus in our own unique manner. The intensity of the response to a pain stimulus is largely subjective, meaning the severity of the pain can most accurately be defined by the person with the pain, rather than by other observers.
Our individual pain perception can vary at different times, even in response to the identical stimulus. For example, an athlete during competition may not be able to feel the tissue injury of a cut or a bruise until the competition has finished. We may feel more or less pain depending on our mood, sleep pattern, hunger, or activity.
Pain management can be simple or complex, depending on the cause of the pain. An example of pain that is typically less complex would be nerve root irritation from a herniated disc with pain radiating down the leg. This condition can often be alleviated with an epidural steroid injection and physical therapy. Sometimes, however, the pain does not go away. This can require a wide variety of skills and techniques to treat the pain.
The treatment of pain is guided by the history of the pain, its intensity, duration, aggravating and relieving conditions, and structures involved in causing the pain. In order for a structure to cause pain, it must have a nerve supply, be susceptible to injury, and stimulation of the structure should cause pain.
