When Will I Be Able To Breathe Properly After Deviated Septum Surgery?

I'm 5 weeks post-op. My right nostrel is now NARROWER & no air comes through it! My left nostrel is ok unless I'm lying down. It feels like there's an OBSTRUCTION in upper part of my nose where the bone is. It aches. I also have ear-ache when I'm lying on my sides. My surgeon said it can take 6 months for swelling to go down & recommends antihistamines, but I'm wondering if I have enlarged turbinates? Or whether he's right and this is normal & I will get better?!
