Does blowing nose frequently damage my nose after septoplasty and turbinate reduction?

I'm 2 weeks post-op and just caught a cold. Things were starting to feel better after surgery. But now i caught a cold or sinus infection. It's terrible, can't breathe at all through the nose now. I use saline every day. However I need to blow my nose all the time now, am I doing any damage to my surgery results? I can't help it. Don't know what else to do, not allowed to use xylometazoline etc. As I had a 5 year addiction before surgery.
