I have had significant left side abdominal pain for several years with no relief. Have had colonoscopy 3 years ago, ultra sound, c/t scan, MRI, even a spinal tap with no diagnosis. Suffer from chronic constipation that is not relieved byOTC laxatives, a GI gave me some Linzess which works at times. Now I am suffering left hip pain and sciatica that may or may not be related but seems more than a coincidence that it to is on the left side. The colonoscopy revealed extensive diverticulosis.
