hello and welcome to health care magic,
Your lobe seems to have infected and although it involves just a proper medication and cleaning it has to be done by an ENT so that any scarring or permanent injury
can be avoided.
So do not do self cleaning and consult an ENT as soon as possible who will also medicate a proper combination of antibiotic and anti inflammatory medications along with local cleansing.
In any case keep the area dry and clean and wait for it to get cleaned and healed completely.
