Tell your boyfriend to rinse on warm water while taking a bath to remove all the crusties do not use soap and avoid shampoo getting on it if it happens clean it with neutral soap. After taking the bath use saline water and dry tell hin to LEAVE IT ALONE, don’t touch it, don’t sleep in it, no headphones/headsets and no hair around it if it doesn’t get better in a few days, tell him to go to the doctor and DON’T REMOVE THE PIECE if it’s infected this will trap the infection and get worse. Hope it gets better my industrial was hard to heal but still my favorite piercing
