Hi i think i have an ingrown hair on my vaginal lip, is there any fast ways i can heal it from home without going to see a doctor?

Warm soaks: This would be an unusual place for an ingrown hair to occur. Quite possibly this is actually a small inflamed cyst in this area. Sometimes frequent warm water soaks (don't burn yourself!), such as 3 or 4 times a day will encourage this to open and drain. If in the course of the next several days this is improving, wonderful. If over this time frame it is worsening, then see a physician.
