Normally bowel cancer does not cause the occurrence of right sided back pain, but if the bowel cancer has metastasized, symptoms such as right sided back pain or bone pain may occur. Patients with early stage bowel cancer usually show symptoms such as change of bowel habit, increased frequency of bowel movement, abdominal pain, bloating, diarrhea, fatigue, fever or difficulty in defecation. If early stage bowel cancer is not controlled in time, distant metastasis may occur, such as liver metastasis, lung metastasis and bone metastasis, etc. If the patient’s bone metastasis is located in the right lumbar vertebrae, it will trigger the patient to experience right side waist pain. Right-sided back pain can also be caused by right-sided muscle strain, right-sided ureteral stone obstruction, acute appendicitis, right-sided salpingitis, etc. It is recommended that patients with right-sided back pain go to the hospital in time to do the relevant examinations, differential diagnosis, and reasonable treatment under the guidance of professional doctors.
