Pain is an unpleasant sensory and emotional experience resulting from or defined as actual or potential tissue damage. Pain can be mild or severe. Pain can be acute (short-term) or chronic (long-term). Pain can be a useful symptom for a person, a sign of physical danger. Pain prompts us to change our behavior to reduce whatever is causing the pain. Because whatever it is that causes pain will eventually damage our tissues. But pain can also be a symptom that everything has gone catastrophically wrong. In this case, it ceases to be useful, on the contrary, it drains our energy and leaves us tired.
How Does Pain Perception or Pain Sensation Occur?
There are receptors and sensors all over our body, which we call receptors. Some of these sensors are deep in the body. It gives information about swollen joints, overfilled bladder, tense muscles or damaged organs. Sensors located on the surface, on the skin, warn in cases such as burns, cuts and crushing. So these sensors usually appear in response to a tissue damage signal. When there is damage anywhere in the body, some chemicals inside the cells flow out. These chemicals stimulate and activate pain sensors. At the same time, when there is any damage to the tissue, the body sends immune system cells to that area to heal it. There is swelling, which we call edema. An inflammatory process, that is, non-microbial inflammation, begins in the area where tissue damage occurs. Immune cells that come to repair the damage cause inflammation while also stimulating pain sensors. This inflammation is the body's self-repair mechanism, but it should disappear after its work is done. Most of the time, the body balances this very well. Sometimes the inflammation initiated by immune cells lasts longer than it should and becomes chronic.
Pain may be accompanied by other symptoms such as nausea, dizziness and weakness. When pain is felt, the body's first response is usually to reduce movement. Pain is actually a warning that prevents you from causing further damage to our body. Pain makes it difficult for us to do our daily tasks and restricts our movement. < br /> All pain sensors send nerve extensions to the spinal cord. These extensions activate the spinal reflex, where spinal nerves send orders to your muscles. When something pricks the tip of your finger, we immediately pull it back. This is a spinal reflex. Pain information is also sent upwards, to the brain.
