My husband has a chronic lower right back pain. He does get some relief with Advil, but this problem has persisted for years. He will not take Advil daily or weekly for that matter. Has had digestive problems all his life, from irritable bowel to duodenal ulcers 20 years ago. He has had numerous abdominal ultrasounds in the past. Had his gallbladder removed 4 years ago due to a non-functioning gall bladder diagnosed with a HIDASCAN. This pain was relieved post op for almost a year, but has since returned. Seems to disappear when he lies down on his back. His concern is his kidneys. Doesn t feel like muscle strain or spine problem.
