I had an abscess on my left buttocks and had it lanced about a year ago. Well I ended up with one on the right side and recently had it landed two days ago. After the first one 2 days later the packing came out on its own and healed nicely. Withthis one I had to pull the packing out myself. I was advised to get it repacked after the 2nd day. I'm lucky to have been able to buy bandades. I can't afford to go and have it repacked. Can I just keep it covered with a large band aid? Will it not heal? Please help
