Perhaps you bent the wrong way while lifting something heavy. Or you're dealing with a degenerative condition like arthritis. Whatever the cause, once you have low back pain, it can be hard to shake. About one in four Americans say they've had a recent bout of low back pain. And almost everyone can expect to experience back pain at some point in their lives.
Traditional wisdom says that NSAID pain relievers only damage your gut lining if you take them every day for a long time, but recent research disagrees. High-level athletes with stress-related intestinal damage tried taking ibuprofen to improve muscle soreness and recovery. Ibuprofen ended up damaging their gut lining even further after just a couple weeks; it increased inflammation and made their original pain issues worse. In fact, a single dose of aspirin can significantly increase your intestinal permeability.
