Yawning after septorhinoplasty. Will it cause any damage? (Photo)

I keep yawning...and find it hard to control it. I am 2 weeks post op. Sometimes when I yawn, it makes me flare my nostrils which I can't control, and it strains it abit. When the flaring subsides...I feel slight pressure of the nose. No pain, just pressure feeling. I am worried about this, as controlling it is difficult and I am worried it will do damage. :(
