What is the bump on the tip of my nose and why does it deviate to left? What can I do? (photo)

I had rhinoplasty ~4yrs ago. My tip on left has hard bump and nose deviates to left. From right profile appears too sloped with long tip. From left profile appears to be bird beak. What can I do? Had post op bleeding from left nostril and had to go back to OR to have it cauterized 1 wk postop, so I don't want to go back to original PS. Is the bump cartilage or a suture? Do PS make u pay for revision consultation? Thanks!
