The pain on the right side of the stomach near the waist depends on whether it is a male or a female. If it is a male, you need to check the ultrasound of the urinary tract and the examination of the appendix to consider whether it is appendicitis, urinary tract infection or urinary tract stones to rule out these two diseases. In the case of women, in addition to these two diseases, ultrasound of the uterus and pelvis should be performed to rule out any pelvic fluid or tubal problems. It is also necessary to rule out muscle damage in both men and women. In addition to these conditions, the nature of the pain depends on the nature of the pain, so the right side of your stomach near the waist alone is not able to determine what the disease is, but can only be considered from these aspects. The specific diagnosis also needs to see the patient to check the body, and then according to the relevant examination to finalize the diagnosis.
