I'm having lower left side pelvic pain. after urinating it gets a bit worse, numbing like pain. i have some discharge, thick white no odor.

Infectious: You might have an infectious process going on that should be evaluated. It may be something other than a simple uti.

Possible vaginitis: If you are having pain during or after urinating, this could be the sign of cystitis or bladder infection. Additionally, you may have a yeast infection, which typically presents as a cottage-cheese like discharge with itching and/or burning. Either way you should seek care from your gynecologist or medical doctor.
