The painful stomach and the inability to relieve the bowel movement with nausea and vomiting may be due to acute gastrointestinal infection caused by the consumption of unclean food, which usually occurs around the umbilicus and has paroxysmal attacks. If the pain is obvious, you can take antispasmodic drugs, such as 654-2 or belladonna tablets, to treat the symptoms. If nausea and vomiting are obvious and no medication can be taken, it is recommended to seek medical attention for symptomatic treatment such as infusion. It is also not excluded that the disease is caused by intestinal obstruction. If this is the case, the clinical symptoms of vomiting will be more obvious, and the clinical symptoms of non-defecation and non-exhaustion may also occur. For this disease, it is recommended to seek medical attention to improve the examination and timely treatment after the diagnosis is confirmed.
