Can irritable bowel syndrome cause lower back pain?

Absolutely. Anything that creates gas in your stomach or intestines can cause bloating, and this can put pressure on your spinal column and the nerves of your lower back, creating pain for you. This can usually be relieved quickly in many people with something like Rolaids or an acid reducer tablet. If that doesn't work, a walk can help settle your food, improving digestion. Walking is also great for many types of lower back pain, so it's a win-win. You can't go wrong with some exercise, especially when it's tailor-made to help reduce the symptoms of two different problem you're having.
