If the vagina feels hot and painful or itchy, it is usually caused by vaginitis, but it can also be caused by other gynecological infections. Normally, the vagina has lactobacillus bacteria, which keeps the vagina clean and kills harmful foreign bacteria, but if you don’t pay attention to your hygiene or have an unclean sex life, this can easily lead to bacterial invasion and cause inflammation. If women suffer from urethritis or cystitis, it may also cause tingling sensation in the vagina. It is recommended to go to the hospital for routine leucorrhea and urine tests to clarify the diagnosis and then use targeted medication. Drink more water to help flush the urethra and vagina, and avoid spicy and irritating foods in your diet.
