Could take as long as a week of soaking to soften up the bumble and it may just open on its own after good soaking and using the drawing salve. But that isn’t the norm even if there isn’t a scab you maybe able to still open by soaking and using a pair of sterile tweezers to pull it open, main thing is getting that plug out. Some cut I like to give it time and so far I haven’t had to cut just use tweezers and open and get the plug out. Main thing is catching early before the infection hasn’t spread to joint and bone.
