Pelvic Inflammatory Disease. Pelvic inflammatory disease can cause lower back pain and lower abdominal pain. FamilyDoctor.org states that pelvic inflammatory disease is an infection of any of the female reproductive organs, including the uterus, fallopian tubes or ovaries.
(See also Overview of Digestive Symptoms.) Pain in the middle of the chest or upper back can result from disorders of the esophagus or from disorders of the heart or aorta (see Chest Pain). Symptoms may be similar. Gastroesophageal reflux disease (GERD), caused by stomach acid splashing up into the esophagus, can cause a burning sensation or a tightness under the breastbone (sternum), which may resemble the pain of heart disease.
