Burning, itching or pain in the vulva during urination is generally diagnosed as acute vulvovaginitis, which is seen as swelling, congestion, erosion, sometimes forming ulcers or patches of eczema. Patients feel burning, itching or pain in the vulva, especially during urination. In severe cases, the inguinal lymph nodes are enlarged and painful, and the body temperature may be slightly elevated with an increase in white blood cells. In diabetic vulvodynia, the vulvar skin is red, thickened, often brown and scratched. Because urine sugar is conducive to the growth and reproduction of mycobacteria, it is often complicated by Candida albicans infection.
