My boil keeps leaking advice please

hi there i have a boil on my left bum cheek i went to doctors they gave me antibiotics this morning during the might it felt wet and the boil has burst i jumped straight into the shower cleaned and got dressed again and it just keeps slowly leaking out i was wondering how to go about this should i just wear my boxers and let it keep leaking out or should i let it air out and if so how ?

thanks for any advice in advance
