Thanks for the query,
Most of vaginal burning isn't a major concern. But because they can be symptoms of an infection like bacterial vaginosis
A number of chemical substances like creams, douches, condoms, contraceptive
foams, laundry detergents, soaps, scented toilet paper can irritate the vagina and thus burning sensation.
Avoid using any of these substances.
Maintain personal hygiene.
Get a swab test to rule out vaginal infection
