Developed a sudden indentation on one side of my nose tip, how to correct? (Photo)

My nose has always seemed to tip to the left but now it tilts more to left than before, there is also a hole and shadow on the right side of the tip that was not there before. I have not received any hit though I have had trouble breathing and smelling for a while now, could it be a deviated septum or cartilage collapse? If so, what is the best way to proceed?
