Abdominal pain
Pain is an unpleasant sensory and emotional experience of varying intensity associated with actual or potential tissue damage. Special receptors are irritated at the site of tissue damage, and a nervous impulse is born, which is transmitted to the brain through sensory nerves, where it is perceived as pain. Pain is followed by a negative emotional response, accompanied by fear, agitation, or depression – suffering. If pain persists for a long time, a person’s behavior changes: they talk about pain, worry, constantly visit doctors or pharmacists, seek relief, their attitude changes, their facial expression changes. Pain can be caused by any tissue damage – mechanical, thermal, chemical, inflammatory. Suddenly starting, lasting no longer than 1 month, pain is called acute. Chronic pain is called when it lasts more than 6 months. If the pain lasts more than 1 month but does not exceed half a year, it is considered subacute.
