Hi. Thanks for your query. Read and understood your history. Pain in the lower abdomen in a menopausal female person, on sneezing, coughing or moving in a certain way is most probably due to the muscle spasm, sprain in a particular muscle group. Once hurt, every movement of any nature does not allow it to heal. Another most probable reason can be a hernia. Very rarely an internal problem can cause, but then there will be sufficient inflammation that it will be difficult for you to move. I would advise you the following: First all get a physical and per-vaginal examination done by a Gynecologist to have a clinical idea what the problem may be. This is to be assisted by trans-vaginal and abdominal ultrasonography. This will prove the diagnosis and give a plan for further treatment. If required you can certainly ask for a second opinion of the General Surgeon.
