I keep getting pain and discomfort in my lower abdominal and lower back for the pass four days.?

Abdominal pain: Abdominal pain could be from a variety of reasons. In women, gynecological causes are common. Ovarian cysts, endometriosis, or uterine reasons need to be investigated. Bowel reasons such as inflammatory bowel disease, appendicitis could also be the reason. With your previous history of surgery (appendectomy)- bowel obstruction from adhesions is possible. See a physician.
