Pain has different names depending on its onset time, place of origin and mechanism.
Acute pain: It indicates the existence of an event that harms the body. There is a close relationship between the causative lesion and pain in terms of location, intensity and time. Causes include trauma, infection, decreased blood supply to the tissue, and inflammation. Postoperative pain is the best example of acute pain. Acute pain shows the characteristics of chronic pain after 3-6 months have passed.
Chronic pain: It is a complex condition in which psychological factors play a role, changing the person's quality of life, leading people to abnormal behavior.
Somatic pain: It is sudden onset, sharp, well-localized pain originating from somatic nerves, that is, motor nerves and sensory nerves that we can control voluntarily.
Visceral pain: It is pain originating from internal organs. Chemical irritants can be counted among the causes of sudden tension of organs, excessive contractions and decreased blood flow. Visceral pain may be widespread, difficult to localize, or referred to. Changes in blood pressure and pulse rate are accompanied by tension in the muscles.
Deep pain: Pain arising from joints, tendons, muscles and fascia is carried by thin fibers similar to those in the skin and transmitted by the same means. It is usually of the blunt and throbbing type. It is not well localized and tends to spread. Deep pain occurs after mechanical effects such as stimulation of the ends of the fibers with chemical substances and stretching of the muscle fibers.
Superficial pain: It is pain originating from the skin and mucosa.
Reflected pain: Pain originating from some organs and skin tissues may be felt in a place other than the stimulation site. Like heart pain reflected on the left arm, gallbladder pain reflected on the back.
Trigger point pain: Small, round and very sensitive areas occur in the skin, muscle and connective tissue. These points are called trigger points. Trigger point pain is closely related to referred pain. It is most commonly seen in muscles. In acute injuries, it also occurs outside the injury site. These points are activated by pressure, pricking, movement, stretching, extreme heat or cold. The location of many trigger points in the musculoskeletal system corresponds to classical acupuncture points.
Neuropathic pain: Pain caused by structural or functional nervous system adaptations secondary to central or peripheral injury. Pain, which was previously considered psychogenic, has recently been better defined and understood to be neuropathic pain of central origin. Pain due to structural changes such as spinal cord injury, multiple sclerosis, epilepsy and stroke are examples. Neuropathic and neurogenic pain should not be confused. Neurogenic pain is pain that occurs due to peripheral nerve injury without any requirement for neuropathy. Neuropathic pain is also used to describe pain that occurs as a result of metabolic diseases. Pain may occur spontaneously.
