I had septoplasty surgery to my nose 3 days ago. Need to know if I can use a saline spray or saline rinse?

I had septoplasty surgery to my nose 3 days ago. I was awake for it all but num so u didn’t feel much but hear the sound of what was going on which was horrifying. I have the dissolvable packing and they never really told me how long it will be gone or if I can use a SALINE rinse or just a saline spray... they really just did the surgery and sent me out... it was horrible.. please let me know when I should be able to breathe again I am going crazy.
