Why can I still see and feel the dorsal bump after rhinoplasty? (Photo)

I am 1 month post op closed rhino and after 10 days post op I could feel the bone where my bump was before.I asked my surgeon and he said that I might be able to feel it but Not see it.at one month post op I can see the bump. Is this because it has not been reduced enough? I have read that it could be callous formation that smooths out in time? I don't have much swelling and it feels hard. I bumped it one night, was a sharp tingling pain that did not last long and I didn't notice any difference?
