Steroid injection post rhinopseptoplasty-has something gone wrong? (Photo)

I had a steroid injection post rhinoplasIty. The swelling from it went down by day five, except for a persistent hard lump on my bridge. My doctor said I could mould my nose a bit with it and gave me an exercise to do to help tip. Has the steroid affected the bridge and moulded it permanently like this? It still feels a bit weird. I can push/massage it down a little but it comes back soon after. I'm not really sure what to do- hope it's just prolonged swelling. I can definitely feel this lump.
