Do you always need a steroid injection or kenalog injection post rhinoplasty? (photos)

I had a rhinoplasty done about three weeks ago and I honestly hate the result. The bridge is too big and wide for my face, i look like a pig. Im just hoping the in time and the swelling stop that it will get smaller. Im considering kenalog injection to lessen the swelling and hopefully reduce the chance of scar tissue. Or do I need revision to get a thinner nose? Please help
