The burning sensation in the abdomen may be caused by the irritation of the gastrointestinal mucosa by stomach acid or intestinal fluid. This is usually caused by damage to the mucosa of the gastrointestinal tract, such as acute and chronic gastritis, enteritis or gastric ulcers, diffuse intestinal ulcers, etc. These conditions may occur. The symptoms can be relieved by eating appropriate food or drinking warm water to dilute the stomach acid and intestinal fluid. If there is a burning sensation on the surface skin of the abdomen, it is important to consider whether the symptoms are caused by abnormal nerve sensation due to herpes zoster, which, in addition to the burning sensation, may also manifest as small herpes zoster on the abdomen to the waist.
