Washing underwear and socks together may lead to vaginitis. For patients with foot odor, if underwear and socks are washed together, there is a risk of mycobacteria infecting a woman’s vagina, which can cause mycobacterial vaginitis. Therefore, female patients should pay attention to wash their underwear and socks separately. At the same time, you should pay attention to the cleanliness of the vulva, not to wear tight-fitting clothes and chemical fiber pants, change your underwear and underwear regularly, and prohibit the consumption of spicy and stimulating foods. Don’t use lotion to cleanse the vagina, just use water to cleanse the vulva, because repeatedly rinsing the vagina may cause dysbiosis, as the vagina itself has a self-cleaning effect.
