What is this

I’ve called the doctor and spoken to the nurse she has said there’s great reason for concern but they had absolutely no appointments. I can go in and pay more for after hours emergency though. It came up 3 days ago as just a bump under the skin, I left it and just assumed it would go away. Then come 2 days later it was fully inflamed and very red and blue bruised( doesn’t feel bruised) i drew a circle around it to see if it was increasing in size and it has. It’s gotten bigger again since this photo was taken today. I haven’t been able to shave my bikini line as it hurts so much to touch.
