Common causes of left lower abdominal pain in female patients include urinary stones, urinary tract infections, or pelvic inflammatory disease, uterine adnexal disease such as ruptured corpus luteum and torsion of ovarian cysts. For urinary stones, the medication used is lithotripsy granules or lithotripsy flush. For urinary tract infection or pelvic inflammatory disease, cephalosporin antibiotics or quinolones are used, such as cefixime, cefdinir, cefprozil, cefradine or levofloxacin. For ovarian cyst torsion or corpus luteum rupture, surgical treatment is required and medication is ineffective.
