-Bony -Very hard -Does not move -Upper left side of my nose -On the nasal bridge
This looks like something that should be easy to fix. Again, you don't say if you had a rhinoplasty, but either way this should respond to treatment.
The pictures do reveal what appears to be a bony bump.There are a lot of questions that need to be known. Your age and onset of the bump?Any history of trauma? Is it tender?It could be anything, but my guess would be a benign growth like an osteophyte.They can be removed surgically with a rhinoplasty technique
