If the bump feels very hard, it's probably cartilage, and it's probably not going to go away with a cortisone shot, as it sounds you've already discovered. The frontal views seem to show that depression between the hard bump and the bones farther up the nose. The middle image shows prominence of the tip, then the bump, then the depression, then the prominence of the bones. The bones have the appearance of an "open roof" deformity, which is common when a bump is removed from the bridge but the bones aren't then narrowed in position to maintain a nice triangular contour to the upper nose. You'll probably end up having to decide whether to live with this nose or get a revision. If you do opt for a revision, look at all the areas of your nose as well, because you would want the surgeon to address everything that's not to your liking. How *much* to lower that bump, or narrow the bones, or make other changes, such as further changes to the tip? We figure that out with morphs, well before surgery. I'd love for you to see some excellent professionally-designed morphs of what could possibly be done with your nose. Morphs could also help you identify better just what's bothering you, and help you set a goal for the rhinoplasty that's accurate for your tastes. Profile and three-quarter views would be particularly important in morphing your nose. (Side note: in my opinion, morphs should really be done by the surgeon, or he should direct an assistant as she makes the morphs. Morphs should be made with a constant eye to what actually *can* be done in surgery, for that particular nose, and the surgeon has that information and judgment best.) Finally, remember that rhinoplasty is an exquisitely difficult operation to get right, and you should only have surgery if you are able to make yourself very confident in your surgeon's skills. The changes that your nose needs require advanced techniques, and skill that most plastic surgeons don't possess with expertise. It's much better to not have surgery than to have inexpertly-performed surgery. Read my essay on how to stay out of trouble while selecting a rhinoplasty surgeon. And it also discusses how to take photos that are best for online evaluations. And for those who have had previous surgery, it also discusses how to tell whether your first surgeon should be performing your revision.
