Vulvar itching

Sometimes my vulva feels itchy.

It seems to get worse at night rather than during the day.

I wash myself about twice a day.. but I heard it's not good to wash frequently at the hospital.

When I was young, I went to the hospital thinking I had vaginitis, but it wasn't vaginitis.

Sometimes my skin peels and feels stinging... I don't know what's wrong.

I wonder if there are any people who have experienced these symptoms... and whether they have received treatment.
