I have done NeilMeds wound wash twice a day, that with sea salt soak, just a sea salt soak, tried leaving it alone and none of that’s helping! I’ve had it for 4 months today (5.6.19) and I know most cartilage piercings take 6-12 months to heal and I’m fine with that part but not fine with this blister bump thing and it’s so sore :( not infected either, just the painful bump I can’t seem to shake. The earring is made of surgical steel
