###Human: What has caused a sore pimple in my vagina lips? ###Assistant: Hi. Shaving or waxing the intimate areas often lead to ingrown hairs, infected follicles out there. Either you can cut it out with scissors leaving a bit or go for laser hair removal. These problems settle down forever. Do use douches, just cleanse the area with water during bath. For the boil now, give hot fomentation to the local area. The problem will resolve once the pus comes out, the ingrown hair will be seen, and you can gently pull it out with a tweezer cleaned with alcohol.
