The right side of the lower back with occasional tugging pain and vomiting may be due to diseases of the internal organs, such as cholecystitis, gallbladder stones and so on. When the internal organs have lesions, because they share the same spinal cord segment with the innervated area of the lower back, the right side of the lower back may be involved in pain, and when it affects the digestive system, it may also be accompanied by vomiting, such as cholecystitis, gallbladder stones, and so on. The kidneys, as they are retroperitoneal organs with the intestines in front of them, may also show the above symptoms when lesions occur, such as right kidney stones and right ureteral stones. If the symptoms of pain and vomiting are severe or if the symptoms persist without improvement, the patient should go to the hospital promptly for treatment.
