Hi,
I had open rhino with Dr G last Monday. The nurse said I could use the spray from the day after the op but I wasn’t brave enough to use it until about day 4/5 and even then I’ve only used it a handful of times from outside my nostrils. I didn’t find that it had any effect though to be honest. I just gently cleaned around the outside with a wet cotton bud but again, i waited a few days first.
Good luck with your recovery! X
