If a woman has pain on the outside of the labia majora, first of all, she needs to observe whether there is any obvious mass on the outside of the labia majora. If there is no lump and there is simply a local tingling pain and no redness or swelling, it cannot be excluded that it is caused by nerve irritation and can be temporarily observed without special treatment. If there is an obvious lump at the painful labia majora and there is also pus, it is considered to be caused by vulvar boils. This is caused by lack of hygiene and irritation from urine and feces. It is necessary to use povidone iodine solution for local disinfection or sitz bath, and then apply erythromycin ointment topically. After treatment, you also need to observe the regression of the lump. If necessary, oral antibiotics can also be administered for anti-inflammatory treatment.
