Is it normal for my nose to feel dry all the time and to get crust every day 8 month after Rhinoplasty?

My nose just feels really dry all the time and I get crust everyday, specially in the morning when I wake up. I went to see my surgeon on Friday and he said the crust is normal and everyone gets crust and he told me i don't need treatment. I was using saline gels and saline spray and sometimes Vaseline but i stopped per suggestion of my surgeon. but now my nose feels even more dry than before with crusting. could this be an infection, or maybe just a rebound effect from stopping moisturizers?
