Do I have a collapsed nasal valve or is it swelling? 3 weeks post op (Photo)

I had rhinoplasty/septoplasty 3 weeks ago and I had my bones broken and nose made more narrow. However as the healing is continuing, I've noticed that my left nostril feels weak as if my cartilage can collapse any minute. My right nostril has more support. Is this due to swelling? Meaning is my right side more swollen than my right? Sometimes I will see a dent and then sometimes I don't as it continues to heal. Is it possible that my nasal valve has collapsed?
