Pain is mostly associated with unpleasant feelings and is largely despised and feared due to the emotional distress of sensations. However, without pain, humans wouldn’t be able to separate harmful actions from non-harmful ones and wouldn’t let their bodies heal. The sensation of pain is very crucial to the human body as it acts as a defense mechanism by alerting the body of on-going damage to the tissue or potential damage. The importance of pain is even more obvious when diagnosing patients with congenital insensitivity to pain, as their life is filled with terror of being hurt but being unable to detect it, which could ultimately lead to their death. This article dives into this disorder and how it can affect the normal daily lives of human beings, further revealing the vital importance of pain.
