I could be either a urinary or a vaginal infection
. Is there any white or any other colored dischrge, or a foul ordor from the vaginal dischage?
Will need an examination , a urine test and medicition.
Avoid intercourse for some time, and visit a gynaecologist.
Also keep the area clean, wash from front to back after each visit to the toilet, cotton panties, avoid scratching, plenty of water and less tea/coffee/alchol.
