If you have hard bumps on the vulva, consider that they are caused by local hair follicle infection and inflammation. The vulva is rich in hair follicles and sebaceous glands, and the local sweat glands secrete a lot, so the vulva is in a humid environment for a long time, and is often stimulated by urine and faeces and menstrual blood, which can easily lead to local hair follicle infection and inflammation, and form folliculitis. For this situation, you can use warm water to wash the affected area, use iodophor to disinfect, apply metronidazole cream or Bactrim cream for anti-inflammatory treatment. Be careful not to squeeze and scratch the affected area to avoid aggravating the infection. Also need to pay attention to wear loose, comfortable underwear as far as possible, to avoid local friction stimulation and moisture stimulation. Pay attention to clean the area thoroughly after urinating and defecating, and if you are in your menstrual period, pay attention to changing sanitary napkins regularly.
