There is no fastest way to relieve stomach pain. Stomach pain can be seen in gastritis, gastric ulcer, gastric cancer, etc. It needs to be treated according to the cause of the disease, including medication such as omeprazole, aluminum carbonate, metronidazole, etc., surgical treatment, dietary adjustments and so on. If it is caused by gastritis or gastric ulcer, the commonly used drugs include acid inhibitors (e.g. ranitidine, omeprazole) and gastric mucosal protectors (e.g. bismuth potassium citrate, aluminum carbonate). If Helicobacter pylori infection is present, a combination of acid-suppressing drugs, bismuth and two antibiotics, such as amoxicillin and metronidazole, is also needed. If it is caused by gastric cancer, surgical treatment and chemotherapy are required. Commonly used drugs for symptomatic treatment are antispasmodic painkillers such as atropine.

However, it should be noted that the medication must be used under the guidance of a doctor, do not take the medication on your own.
