It might be mostly due to urine infection nothing else. First of all I would like to say drink as much water as you can at-least 5 liters per day because it is very useful in your case. You can take tab norflox 400 mg twice daily after meals with tab cyclopam or tab meftal-spaz twice daily after meals if pain is there with tab rantac or tab famotid twice daily empty stomach at-least one hour before any meal. Maintain hygiene of your body and private parts either by simple wash with soap water or you can use v-wash vaginal gel.
