If it's only been two days and the fish is fine otherwise, (eating and swimming normally, no white or gray fuzzy growth anywhere on his body), then I'd be more inclined to watch and wait.
Even though your water parameter numbers are good I still might up the frequency of partial water changes for the next couple of weeks as well as doing anything you can to improve water movement.
If there's an ongoing aggression problem and this fish is continually being chased or chasing then it may slow the healing process down. (Stress, re-injury)
