Can I Inhale Steam After Rhinoplasty?

hello Doc! i had rhinoplasty 20daysago.I still have swelling on my face,congestion in my nose and cant speak properly.i apply ice twice in a day.since it is winter season i have developed cold.At nights by nostrils give me burning sensation.i'm able to blow air out to remove the flem,the scabs had also got out but when i'm removing it got attached to the stitch inside the nostril adjacent to tip got out.due to ingorance i pulled off the stitch.Does it effect the shape?can i take steam for cold?
