6 years post nose job, hit my nose and it changed. Do I need a revision rhinoplasty? (Photos)

I had a nose job 6 years ago and was really happy with the results however I hit my nose really hard and since then it has changed a bit. I have what feels like a ball in the nose tip and it’s getting bigger, I had a ultrasound on it and the doctor wanted to get a biopsy using a hole puncture but I haven’t done it because I don’t want it more damaged. What could this be from? Not sure if it was going that way anyway…the bump also appears to have less pigmentation. Will I need a revision rhinoplasty or are there any other treatments that could help?
