I will be 8 weeks post op on Tuesday and for the last 7 days I have had a terrible cold, and have been blowing my nose alot the last few days. I had a cartilage graft put in the right side of the nose to build it up and this morning when blowing my nose I accidentally banged the graft area and I have noticed that I can feel the graft on the inside. Is it possible I damaged the graft with this cold? How long do cartilage grafts take to heal? Is it normal to be able to feel them?
