Its too early to think that surgery was good/bad.Give time to heal it.I can Not comment about the surgery.
what You can do is use Physiomer Nasal Spray
(normal saline spray to keep your nasal mucosa healthy and help in healing better) 2 puffs both nostril two times a day
ointment for local application in nose two times a day.
there is always a nasal cycle
in nose one nasal cavity
is wide and other is narrow then reverse occurs.So do not worry .
Do not pick your nose it will traumatize the nasal mucosa/skin.
