Is this a mid vault collapse or something else?

I had a primary Rhinoplasty in October. I have medium thick skin, this was told to me by my surgeon. I am still swollen at the bottom of my nose.I saw my surgeon 2 months ago and was told it was swelling. Is this level of assymetrical swelling seen at 8 months post op? I am concerned it is a mid vault collapse that seems to be only effecting the right side (my right) of my nose. There is no pain but it does feel different that the other side of my nose.
