OK.first off I am sexually active and 21. Lately I have been experiencing sickness such as diarrhea, nausea, and lower back pain. I noticed like a month a go that I had a bump on my vagina lip. I burst it ( yea I know nasty) like everyday and everyday white or yellowish puss will comeout. After a while it went down so I just thought it was gential acne. But then today I noticed it again in the shower. Yet again I burst it and then time puss continue to come out but greenish white color. Can anyone give me an idea of what may be wrong? By the way both times I noticed to bump I was on my period if that helps. Thanks for reading
