Staining Clothes

I had a really large boil that burst a few days ago and had been continually draining. It had stained my clothes and my sheets already and I don’t know how to keep it from draining through my bandages and clothes. I woke up five times last night to get up because I kept draining so much. I hate that I’m ruining my clothes so much. Does anyone have any tips or things they do to try to prevent draining through clothes?
