Tampon allergy mainly manifests as itching and redness at the vaginal opening after using sanitary napkins and small bumps in severe cases. The symptoms will be significantly reduced or even disappear when you do not use sanitary napkins or switch to another brand of sanitary napkins. Women have delicate skin on the vulva, so using sanitary napkins during menstruation is less breathable, and when the interval between changing sanitary napkins is long, the skin on the vulva will be itchy and red, and small pimples will appear, so you need to change to another brand of sanitary napkins, don’t use medicated sanitary napkins, try to choose cotton-faced ones, and sanitary napkins should be changed in 2-3 hours. Wash your vulva with warm water every night. When your menstrual flow is low, you can use toilet paper instead of sanitary napkins to increase the breathability. Change your underwear every day, and choose cotton and loose underwear.
