Hi ! From your history it seems that you may also be having an associated left ureteric calculi which is causing such severe pain
.To know this, your treating physician may advise you for an ultrasound
of the abdomen or an intra venous pyelogram
on which will depend further course of action.
In case of females, pelvic inflammatory diesease may also give rise to such symptoms which is also associated with a urinary tract infection
I think you need to be reviewed by your treating doctor. Wishing you an early recovery.
