Dent and increasingly appearing bump 6 months after rhinoplasty (Photo)

I had rhinoplasty 6 months ago and was not satisfied right from the start. The bridge of my nose has already had a visible dent on the right side after the cast came off and now, as the swelling subsides, it seems only to become worse. A few days ago, the area right above the supratip started to feel and look a bit bumpy, which is pretty worrying to me. It feels hard as bone, so I doubt that it's swelling. Is it still possible for a lasting bump to form at this stage?
