***10 points*** Off-White substance coming out of skin from nose?

Ok so I know the first thing that comes to mind is 'puss'. But the substance is harder than that of puss and resides inside the skin on my nose. I eventually pull it out with tweezers where it comes out almost like a maggot, only much more smaller than one. It is 3mm long on average and no it's not alive lol. When i pull it out it lives quite a noticable hole in my nose. The hole eventually heals over time. What is it??
