I have a hump on the left side of my nose. It feels very thin and pointy. The right side is just normal (Photo)

Based on you photos, the bony prominence appears to be due to step off between the nasal bones the underlying nasal cartilages. This is often caused by previous trauma but can be genetic as well.

A cosmetic rhinoplasty the surgery of choice to correct these deformities and reposition the tissue in the nose for better aesthetics. This often involves removing the dorsal humps and narrowing the width of the nose. This can be achieved through a closed or open approach but is typically done in the OR under anesthesia.

A detailed examination will help delineate the best treatment. Consultation with a plastic surgeon certified by the American Board of Plastic Surgery would be the next best step.

Thanks for your question.  That thin raised area can be due to either prominent nasal cartilage or bone.  It is likely more prominent on you due to your thin skin and likely previous nasal trauma in the past.  Don't worry it can easily be fixed thru a rhinoplasty.  Please see a qualified rhinoplasty surgeon for best results.

Hello and thank you for your question. This is likely but could also be cartilage.  This can be fixed with a rhinoplasty.  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.

Thank you for your question and photos.  I call this a "dorsal nasal spur".  This is seen in thin-skinned patients and is a deformity of the junction of the nasal bone and upper lateral cartilage.  And as you mentioned, it is typically associated with a depression of the cartilage. Correction would require a rhinoplasty to gently file down the bone and support the upper lateral cartilage.  I hope this helps!

It is likely that the bump you feel is either bone or cartilage. It is best to be seen in person, but the only way to permanently remove it is by rhinoplasty.
