Dorsal bump back after revision rhinoplasty surgery?

I initially had surgery in Feb 2015, and then revision rhinoplasty in November 2015 to smoothe down the dorsal bumps that developed after the first surgery. However, about a month after the revision surgery I felt the bumps start to return, and now 11 months on the bumps on the bridge of my nose are now visible again and I feel as if they are getting bigger each day. Do I need to get them shaved down again or will they just come back again? Or will they eventually disappear if I keep waiting?
