Why is my Nose More Swollen on Some Days? What Can I Do To Keep The Swelling Down?

I know this Q is probably asked way too many times and Ive read them all. However, I had my rhinoplasty two months ago. My nose was swollen before too but still looked a bit refined. Now, after two months the tip is so swollen it looks like a balloon. It also throbs from time to time. I'm not sure why but would really like to find out what I can do to keep the swelling down. And yes, I am aware that I won't see the final results until one year. Thank you. :)
