Vaginal pain during urination may be a mixed infection of the urinary tract and vagina. Anatomically, the two organs, the urethra and the vagina, are very close to each other and cross infection can easily occur between them. The typical clinical symptoms of urinary tract infection are urinary urgency, frequency and painful urination, and in some cases, lower abdominal pain and fever when the symptoms are severe. The typical clinical manifestations of vaginitis are increased leucorrhea, a change in color, which can be yellow or yellow-green, and often accompanied by significant vulvar itching. In some cases, the patient may have a urinary tract infection first, but if the urinary tract infection is not treated in time, the inflammation will infect the vagina and the symptoms of vaginitis will appear, which are accompanied by pain in the vagina during urination.
