There are many causes of chronic abdominal pain, and if the cause of chronic abdominal pain cannot be identified, first of all, more detailed examinations are needed, such as gastroscopy and colonoscopy, and sometimes angiography. Because in a small number of patients, the pain is caused by spasm of blood vessels, and in this case the cause can only be further clarified by the corresponding angiography. In some patients, the pain is caused by tuberculosis or infection in the abdominal cavity, so a tuberculin test or a spot test is required. If after all the tests, no obvious cause is found, one can go to the hospital and find a doctor to prescribe herbal medicine for treatment, which can be combined with abdominal physical therapy to relieve the corresponding symptoms. During the treatment period, patients also need to adjust their diet, such as not drinking alcohol and not eating spicy food, etc.
