Am I allergic to ointment I’m using for internal stitches after rhinoplasty?

11 days post op rhino I’ve pretty much stop leaking any blood until I put bactrician zinc in my nose very gently then I’ll start bleeding and it’s always in the same spot from where my internal stitches are, also my nose starts to burn a lil from the ointment. Is it normal to bleed and burn a little from stitches only after the ointment has been applied? Am I allergic to it? My doctor said not to use it if it irrates me but I feel I should have some type of ointment on it to keep it moist in there.
