My younger brother has had a mild, persistent pain on the left side of his navel for several days, and it hasn't improved. What could be causing this kind of abdominal pain near the left side of the navel?

Dr. Jin Zhongkui
Dull pain on the left side around the navel may be caused by factors such as cold exposure, excessive exercise, or ureteral stones. If the abdomen is exposed to cold, if strenuous physical activity leads to abdominal muscle strain, or if insufficient water intake results in kidney stones blocking the ureter—causing ureteral stones—these conditions may all lead to the aforementioned symptoms. It is recommended to visit a hospital for examination to determine the exact cause and receive timely treatment.
