I have had pain in my left lower abdomen for 2 days, sharp and dull and achy. it is worse with movement and wakes me up at night.

If not constipation,: If it is not constipation (collection of stool in the left lower abdomen) that goes away with a bowel movement, then her primary care doctor can check to see what the problem might be. The doctor can check to see if there is a mass of some kind in the abdomen or pelvis. Sometimes an infection, diverticulitis, an unusually-located appendicitis, or some sort of tumor, can cause such symptoms.
