For the last 2 weeks I've had continuous pimples in the crease of my nose. I'll have 1 big one for a few days and then when it goes away, another on the other side of my nose crease will appear! They are particularlly big and sore! What do these mean and how do I make it stop! I'm 15 and have had many pimples around 2 years ago but now I normally have clear skin??
