I'm not sure how to answer this question. I don't know if you've had surgery or if you've been injured or if you knows simply cracks when you push on it. If you had surgery or a recent injury stop touching your nose and check in with your surgeon. If you have not had surgery and have not been injured some clicking one pressing on some cartilages of the nose is not unusual. I get feeling you've had surgery or some sort of trauma so you need to just go see your doctor. Chase Lay, MD double board certified facial plastic surgeon
