Still very early in the post op stage. But after 3 months if hump still present than not healing/swelling issue...
Yes, this can be swelling. One of the reasons rhinoplasty is so difficult is that after surgery, the nose goes through a lot of changes. You will need to be patient for your end results, which you won't see for at least 6 months. I tell my patients to wait a year for their final result. Tell and show your surgeon your concerns. Massage, steri-strips, or steroid injections may be recommended. Good luck.
It is normal to have swelling after Rhinoplasty. This can make it appear that you still have a "bump" on your nose. Some people swell more then others and this can depend on how large of a bump you had before. Show your surgeon the area you are concerned about. Occasionally taping the nose or massage of the area can help it resolve faster. Some surgeons will inject some steroid in that area as well to help the swelling go away faster. Every situation is different. This will depend on what was done during surgery and what your nose is doing now.
