I had a boil on my vagina and it popped a couple days ago now i have a lot of vaginal discharge like brown and red sometimes black! is this normal?

See your gyne ASAP: You probably had a Bartholin's cyst that came, to a head and burst .You should see your gynecologist immediately for immediate follow up treatment.

Boil vagina: Brown and red and black discharge coming from any orifice in the body cannot be normal. Your boil is a combination of pus and blood (fresh and clotted). You should be seen by a clinician as soon as possible for an examination in order to determine the extent of the abscess.
