Irritable bowel causes chronic pelvic pain. To relieve chronic pelvic pain, doctors may recommend a medicine, hormonal therapy, or surgery to try to relieve your CPP symptoms. Your doctor may suggest a narcotic or non-narcotic pain reliever such as aspirin, Tylenol, Advil, Demerol, or OxyContin to help manage your pain. In addition, your doctor may also suggest counseling, physical therapy, changes in your diet, or exercise to help with your CPP.
