The current IASP definition of pain is “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms.” Pain is an unpleasant sensory and emotional experience associated with, or similar to that associated with, actual or potential tissue damage. Pain is always a personal experience that is influenced to a greater or lesser extent by biological, psychological and social factors. A person's ability to feel pain is an essential component of the body's ability to heal. Pain is the body's way of telling us that there is an injury and we must do something about it to ensure that it heals. An important consideration when talking about pain is the fact that one patient's pain is not the same as another patient's pain, even if they have suffered similar injuries.
The perception of pain, in fact, is a subjective experience, influenced by complex interactions of biological, psychological and social factors. Pain is a signal in the nervous system that something may be wrong. It's an unpleasant feeling, such as a prick, tingling, sting, burn, or pain. Everyone feels pain differently, even if the reason for the pain is the same. The pain can be sharp or dull.
It can be mild or severe. The pain may come and go or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, or pelvis, or you may feel it all over your body. Pain is a complex experience that consists of a physiological and psychological response to a harmful stimulus. Pain is an alert mechanism that protects an organism by influencing it to withdraw from harmful stimuli; it is mainly associated with injury or the threat of an Injury.
The concept of gemeingefühl, or “kinesthesia”, by the German physiologist and comparative anatomist Johannes Peter Müller, was another of the creative etiologies proposed for pain. For example, it was considered that the concept that pain deserved special mention and nociception were not synonymous.
