This was a pimple which developed 3 weeks back. It was small and grew and again became small post which i tried prick it. Suddenly overnight it became big and red like this it has been like this over a week now as shown in the picture. Its quite smoother than pimples. I had 2 like this before too I had to forcibly prick and remove them. I am a teenager and my nose gets quite oily in the mornings
