Ear piercing infection. Wound heals.

Hi my three yr old doctor ear piercing site got inflamed due to tight back screw but no pus collection... applied supirocin b plus for five days as doctor advice n then discontinued for six days...it's still not cured completely n inflammation persists n she complaining of pain when wearing earring... doctor told to continue back again ointment until inflammation cures...is steroid combination necessary?NW I started to use supirocin ointment alone without steroid...will this be enough n for how many days to use... already her ears infected once at her 10 months n this is her second piercing so I want her hole to get closed for sure... doctor asked to remove earring to allow it to breathe n heal...hw also suggested to inbtw few hrs wear earring for an hour n remove until wound heals...but each time finding difficult to put earrings...since screw is touching ears, he said is not getting cured completely...pls suggest an opinion...is steroid combination safe to use until wound heals...
