What causes the pain in the lower abdomen in a healthy person?
Patient: 20 male, 5'11"  medical history? n/a i've been healthy, nonsmoker, nondrinker, good diet and exercise.   From my perspective, my lower left abdominal area, it has a weird feeling to it.  it doesn't really hurt, its almost as if there is a bubble there and its just slightly discomforting.  just wondering if i should get it checked out or what it is? Doctor: HI.Thanks for your query.Read your history and nice to know about your lifestyle.the weird feeling in the of bubble in left lower abdomen needs to be investigated .I would advise you the following:First of all a good physical / clinical examination by a General Surgeon to get a clinical diagnosis.Colonoscopy and sos biopsy.ultrasonography of the abdomen and pelvis.X-ray of the abdomen in standing position to have a diagnosis of a volvulus of the sigmoid part of the large bowel. The treatment will depend upon the findings.
