Nose bridge feels pinched and is STILL sensitive to the touch over 4 years post-op. What does it mean?

4 years post-op, I still feel pinching on one side of my bridge 24/7. If I touch my finger to that area, it is very sensitive. It seems there is a lack of bone/cartilage there in comparison to the other side of my bridge. If I lie in bed on the side opposite to my pinched bridge, I feel gravity pressing on the bridge, and it makes me hesitant to sleep on that side. Is my nose still not settled? Is there anything I can do to prevent MORE caving in? Would fillers help? Is bloodflow affected?
