How do I remove my bulging lip tubercle? (photo)

Thank you for your question. There are options to enhance the lips around the bulge, or remove it surgically. I suggest that you move forward and consult with a board certified facial plastic surgeon. While your photo is helpful, a correct diagnosis can only be provided after an in-person examination with a more in-depth discussion of your goals related to appearance, cost, recovery time, etc.
Best wishes,

I would not have surgery for this. Instead, I would try to enhance the sides of the lip to "hide" it. I would use an HA filler.

 Hi, I have performed many lip augmentation procedures using dermal fillers or lip implants for over 30 years. From the photos, your upper lip has a prominent central mound and then thins on either side.  Unless this has been created by the injection of a permanent filler that can't be removed, it's best to fill in either side to make the upper lip more full and balanced.  Only in rare instances of truly over sized lips or when the lips have increased in size from permanent injections, should volume and portions of the lips be removed in my humble opinion.  
The upper lip should be approximately 75 % the size of the lower lip for the lips to appear balanced. The lips can be augmented using a dermal filler or a Permalip implant.
Dermal filers and lip implants offer a much more reliable volume for augmentation of the lips than permanent fillers or fat injections which are associated with increased, unwanted, side effects.
Hope this helps.
