No, they did not give him any antiseptic or any creams. She just told me to do the warm compress, that I may see some bleeding tonight, and to give him the oral antibiotics. She did say that they put an ointment on after they were done lancing it.
It's really crazy how quickly this happened. He was fine last night, I noticed that he was licking his butt excessively this morning, gave him a bath this afternoon, and noticed the swelling. Called the vet right away, and luckily they were able to get me in about 1.5 hrs after I called. I was doing research here on YT and random websites, and started to freak out because I read that some can just rupture.
