I have painful white discharge after urination! what should i do?

See remark: Is the discharge from the urethra,that's to say from the urine opening,or from the vagina,or you can't tell ?? If from vagina,douche with 1/2 teaspoon of baking powder in 1/2 cup warm water once or twice a day for 2 days REASON :If you have fungal infection ,alkaline medium like bicarbonate (sodium bicarbonate) helps.If from urine,use AZO tablet 3 x day for 5 days,if no relieve consult M.D,or go to Walgren for help
