It seems that a septal hemataoma or abscess
was drained one week after your septo-rhinoplasty
. Was nasal packing done post-op? It is possible that the drainage
was insufficient. It is also possible that the excessive packing on the right side has caused adhesions on the left. Ideally you should be examined again. You should be on medications to reduce swelling / infection. If there is a doubt, a CT PNS Scan will settle the issue. Corrective surgery, if required, can be carried out later.
