Hi so for a couple of weeks I've had a swollen lymph node in my groin area. I was given antibiotics to take for seven days it didn't go away but I did get better. So I called the doctor and they scheduled a sonogram to see what would be the next step. I missed my appointment but the next day during work it popped but I didn't notice until later in the day when I went to the restroom. It was just a bunch of puss. It's been 3 days now and it still comes out but very little what should I do
