Which condition is MOST likely to refer pain to the lower back?

• A. Hiatal hernia
• B. Appendicitis
• C. Gall stones
• D. Kidney stones

Answer: (D)

Pain that refers to the lower back often comes from structures whose nerves share pathways with the back region, and kidneys are a classic example. The sensory nerves from the kidneys enter the spinal cord around the T10–L2 levels, so when kidney tissue is irritated or a stone causes intense injury, the brain can perceive that pain in the flank and lower back area. Kidney stones create sudden, severe flank pain that can radiate toward the lower back or into the groin as the stone moves along the urinary tract, which is a hallmark pattern of this condition. In contrast, hiatal hernia typically presents with chest or upper abdominal symptoms like heartburn; appendicitis starts around the navel and shifts to the right lower quadrant; gallstones cause right upper quadrant pain that may radiate to the right shoulder blade or back but not as a predominant lower-back pain pattern. So the described lower-back referral aligns most closely with kidney-related pain.
