Thank you for the query.
Lower left abdominal pain can be caused by urinary tract infection
, ovarian cyst, ovarian infection
. Such pain associated with back pain and same side leg pain indicates urinary tract infection. With this condition, frequent urinating and pain while urinating can appear.
It is advisable to have urine analysis and abdominal ultrasound. If no findings, gynecologist consult and transvaginal ultrasound
should be also done.
Hope this will help.
