The back pain, before or during bowel movements are associated with various reasons or causes such as constipation, facet syndrome, disc herniations, vertibral misalignment, degenerative arthritis. Often sprains of lower back due to physical activity or imbalanced posture can cause back paid during bowel movements. Benign or malignant tumor in any internal organ can also cause such back pain.
