Pressure and throbbing 7 months post revision rhinoplasty. Can this be swelling?

7 months ago, I underwent a 5-hr revision rhinoplasty due to my thick skin. Initially, I experienced migraines, which subsided after 2 months. At 4 mos, I received a steroid injection to reduce swelling. However, at around 5-mos, I began experiencing random congestion, throbbing pain on my nose bridge, & severe migraines. These symptoms persisted even after saline rinses, sometimes causing red blood vessels in my eyes.Can this b swelling,surgeon didn't mention issues nasonex didnt help
