Is my nose fixable and what is this bump on this side of my nostril? (Photo)

It looks *very* much as though the "bump" is part of your right tip cartilage. The tip is made up of two cartilages, one on the left and one on the right. It looks so much as though the bump is part of the right tip cartilage, which is prominently visible underneath the skin because 1) your skin is not too thick, and 2) because the cartilage is strong and has a strong arch to it. On the third photo you posted, the tip seems unnaturally sharp and prominent because we are seeing that cartilage's prominence. In a revision operation, that cartilage would be changes so it doesn't stand out and make a bump, and so that it doesn't affect the three-quarter view, except in a *good* way.
How *much* to alter the cartilage, or change that three-quarters view, or make other changes? 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.)
Remember that revision 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 quite advanced techniques, and skill that most plastic surgeons don't possess with expertise. For most noses, 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. It also discusses how to tell whether your first surgeon should be performing your revision. And it also discusses how to take photos that are best for online evaluations.

Hello, to fix the asymmetry Alar base and columella reconstruction is needed. It has been 2 years and this is the final result of your rhinoplasty operation. Of course in time there will be minor changes but in general that is your nose shape. If you are not satisfied with the result you should consider a revision procedure. As far as I can see from these photos during your rhinoplasty operation, performing surgeon couldn't follow the right path.
