Heavy pressure on my nose 1.5 years after septorhinoplasty. Is it slowly collapsing? (photos)

4 months post-op I started feeling intense pressure on my nose and it lasted for almost 2 months. The pressure disappeared for a while but appeared again 2 weeks ago and it feels like my nose is sinking in. I am so anxious that it could be slowly collapsing because of the weak underlying structure. My nose is still very sensitive more than a year after the surgery. Does gradual nose collapse usually come with pain like feeling intense pressure specifically on my dorsum and tip of the nose?
