Pain is a reaction that we feel when the nervous system is activated due to certain external stimulus. It is a general term that describes uncomfortable sensations in the body. Pain is highly subjective and can either be consistent or intermittent (meaning that it comes and goes).
There are many types of pain, commonly classified as acute and chronic pain. Acute pain means the sensation occurs suddenly for a short period of time, which may go away or progress into chronic pain. Chronic pain refers to pain that is experienced for a longer period of time, or that keeps recurring on and off.
Treatment for acute pain depends on the issue or injury causing the pain. Chronic pain can be more difficult to manage, especially if the cause of the pain is unknown.
In this article we will discuss the three major causes of pain, where they occur in the body and how they are treated.
