Nostril asymmetry and discoloration 1 year post-op - Is there a minor procedure to fix this?

I had an open rhinoplasty a year ago (dorsal hump removal, alar rim+spreader grafts from septum). I don't like my nostrils from the front, one side is lower making the tip look crooked, I hoped it was just swelling but a year later it's still there. In the last few days it's gone red on the dropped side and is sore (after I switched nasal spray and clearing my nose more). Is the discolouration something I need to worry about? Is there a minor procedure to lift the dropped alar rim?
