<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have sharp, sometimes burning lower abdominal pains aroundbelow the navel area. There is also occasionally a sharp pain, almost like a tearing or really bad cramping, on either side of the inside of the vaginal canal. It happens randomly, but it has also happened after emptying the bladder. Not during, just. After. Or if I pull in my abdominal muscles. Or even just sitting. So whats up with that?  <response>: Hi. Thanks for your query. This is the problem of PID, the pelvic inflammatory disease as per the history you have provided of pain in abdomen, sometimes severe, sometimes bad cramps and also on either side of your vaginal walls, and after emptying bladder. Other other associated problems may be of colitis Endometriosis or enteritis and colitis. I would advise you the following:Ultrasonography of the abdomen. Tests of blood, urine and stool. CT scan if required. An opinion and physical examination by a Gynecologist and a General Surgeon. This will get you the diagnosis and the plan for a proper treatment. Sometimes Diagnostic laparoscopy can help for diagnosis and treatment at the same time.
