Had an open rhinoplasty 7 weeks ago to remove my hump, narrow my bulbous nose and lift the tip. Right side of my upper bridge overtime developed a small hard bump and a few millimeters under the bump there's a dent. My general left side looks and feels smoother, fuller, and straighter however. The unevenness from the right side of my nose seem to of caused my frontal view to look as if it's curving. What could of caused my little bump and dent? Should I be concerned? I have thick oily skin btw.
