Over a year ago I took prescription Accutane for my bad acne. While taking the medication, I noticed excessive dryness in my nostrils. Just inside one nostril, I developed hard sores that lasted until a few months ago. More recently I have noticed that there is a swelling inside that nostril (very far inside) that feels soft and wet and nearly blocks all airflow in that nostril. The same nostril usually has small amounts of blood and bloody crusts inside of it, but not an actual nosebleed. Should this be a concern? I am a 23 year old non-smoker with no known allergies.
