Small bump at tip of nose where lateral and medial crura meet, is this damage?

I have a bump between the medial and lateral crura on the right side that feels like its on the cartilage. It feel like a small ball. If I touch it, it kind of throbs and feels a little swollen. I fell into a habit of pushing my nose tip upwards and was wondering if I did it too hard could it damage the cartilage, and what is the treatment? If I touch the nose on both sides at the tip I only feel the bump on the right side.
