Is it normal for my skin to be extremely oily following rhinoplasty?

I received rhinoplasty about eleven weeks ago. Ever since my face has been over-producing oil. It seems that even ten minutes after washing my face, it is extremely oily. I had semi-oily skin before because I am a teenager, but it has never been this bad. It became bad immediately after the surgery. I have tried several products to help calm it down, but nothing has worked. At first I thought it was just because of swelling, but I do not appear to be very swollen anymore.
