Green/Bloody Mucous Discharge after Septoplasty and Turbinate Reduction.

I had septoplasty & turbinate reduction surgery done 2 weeks ago. I had splints in my nose for a week, which were removed about a week ago. My concern is that my right nostril is basically great. It is generally clear and when I use the saline rinse, it always runs clear. My left nostril is a different story. I have to use the neti pot approx every 2-3 hours to remove the blockage and consistently get a lot of green and/or bloody mucous out. Should I be worried about infection?
