Symptoms such as stomach pain and chills can be categorized into two main reasons: physiological phenomena and disease manifestations. A variety of external factors in daily life are the cause of physiological stomach pain, chills and other symptoms, such as improper diet, abdominal cold, emotional stress and so on. Stomach diseases are common causes of such adverse reactions, such as Helicobacter pylori infection, atrophic gastro-sinusitis, gastric sinus cancer and so on. Because the stomach has been attacked by pathogens or tumor cells for a long time, it will cause single or multiple injuries to its muscular tissues, and the sympathetic nerves distributed in the damaged area will cause pain in the stomach area after being stimulated by gastric acid liquid or external substances. In addition, due to the continuous blood seepage from the damaged tissues, the stomach tissues in the state of insufficient blood and oxygen supply will lead to gastric chills, chest tightness, shortness of breath and other symptoms.
