The stomach is located in the upper left abdominal region of the body, so the pain is mainly concentrated in the upper left abdominal region during the spasm of the stomach, and the pain may radiate to the upper abdomen, scapula, back and other parts of the body with the nerve fiber tissue transmission. Most of the intestinal tissues are concentrated in the abdominal region of the body, and when intestinal spasm occurs, the lower abdominal region will be accompanied by significant pain, and some patients may have pain radiating to the pelvis, thighs and other parts of the body. In addition, most of the patients with this condition have complications such as nausea, vomiting, acid reflux, heartburn, and difficulty in defecation. Digestive system diseases are common causes of gastrointestinal cramps in medical clinics, such as acute gastroenteritis, gastrointestinal neurosis, and duodenal bulb ulcers.
