I know I have the bump in the middle, but is it actually BIG? Or unattractive, generally speaking. How do I correct it? (photo)

First of all, neither you nor your nose is unattractive.  If you wanted your nose reduced, the bump could be removed and tip made slightly smaller for balance by performing a standard rhinoplasty.  Again, you're an attractive young lady and I would only recommend addressing your nose if it bothers YOU.  

Hello and thank you for your question. Based on your
photograph, you may benefit from a tip refining rhinoplasty.  You may also benefit from a cephalic rotation
of your tip to turn up your tip slightly and a conservative dorsal hump
reduction.  Make sure you specifically look at
before and after pictures of real patients who have had this surgery performed
by your surgeon and not just a computer animation system.
The most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.

Your nose could be improved with rhinoplasty, which would give permanent improvements in symmetry, shape and remove the bump. You can bring photos of noses that you think would be flattering to your face and these can be discussed. When you meet with a facial plastic surgeon, he or she will consider your nose in balance with your other features and can over the cost of the procedure. I hope this helps.

I would recommend starting with a consultation with a board certified facial plastic surgeon that specializes in rhinoplasty surgery to discuss if rhinoplasty can address your concerns. 
I would recommend writing down the following questions before scheduling your consultation:
1. Are you unhappy with the tip of your nose? 
2. Do you feel that your nose is too wide? 
3. Do you want to make your nostrils smaller in appearance? 
4. Are you looking to decrease the general size of your nose?
I hope some of these questions will help you pinpoint what it is that you don't like about your nose.  Cost will vary due to various factors like anesthesia fees, facilities fees, etc. I wish you the best as you research your options when scheduling a rhinoplasty consultation.
Sincerely,
Philip J. Miller, MD, FACS Double Board Certified Facial Plastic Surgeon

 The dorsal hump is composed of both bone and cartilage which must be shaved down in order to remove it. Osteotomies will then be required to be placed in the nasal bones. Your nasal piercing will need to be left out for several months after the procedure to allow adequate healing. 

Every nose is different and unique to that individual. If
the appearance of your nose concerns you enough to do something about it, it
can be improved with a natural artistically performed rhinoplasty. What would
be the best option and exact procedure would depend on an in
person examination (not just an online consultation) and discussion
about desired outcome. Excellent results can be achieved with either a closed
or open technique.
Keep in mind that following advice from a surgeon on this or any other website
who proposes to tell you exactly what to do and how technically to do
it based on two dimensional photos without examining you, physically
feeling your tissue, assessing your desired outcome, taking a full medical
history and discussing the pros and cons of the operative procedure would not
be in your best interest. Natural appearing results need to be individualized
and what is appropriate for one patient is not necessarily the best for someone
else. I would suggest that you find a surgeon with extensive rhinoplasty
experience certified by the American Board of Plastic Surgery and one who is
ideally a member of The American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable with. You
should discuss your concerns with that surgeon in person.

Thank you for your question.  A nose is a very integral part of a person's face and identity and no two noses are the same, nor should they be!  The most important thing is how YOU feel about your nose, and what would make you happy.  It is also important to know if you have any problems breathing, as surgery on the nose can both be cosmetic and functional.  If you are having some concerns, make an appointment for a consultation with a plastic surgeon.  They will be able to examine you, listen to all of your questions and then have a conversation with you about options that should be able to fulfill your goals and make you feel better and more confident.  More information is always a good thing!
