Hi so I've been using a benzoyl peroxide treatment for about a month now, and it's been working very well. About 5 days ago, a small spot started on the side of my nose and I treated it with bp. It's been growing and finally stopped except the shape is rectangular. I've been icing it 1-2 times a day and washing my face 2 times a day. Anyone know what it could be or how to treat it? It has no head
