How can the bulges under my boobs be fixed? (Photos)

Based on your photos the best likely solution is liposuction. It is difficult to fully determine and provide accurate recommendations without a physical exam. I would recommend seeing a board certified or board eligible plastic surgeon.

Thank you for your question and for posting excellent photos to go with the question.
I would fix this with liposuction.
Fat accumulation over the lower ribs happens in some women. It often feels like a handful of skin but there is usually fat underneath that is causing the small bulge. I find that liposuction does an excellent job in this area.
With any liposuction surgery, there can be loose skin afterwards, however I find that in this location on the body, the skin normally bounces back quite nicely. I also notice on your before surgery photo that you do not have stretchy skin in this area like you did in the other areas of your tummy. However, I also note in your first photo that there is a crease in your midline upper tummy when you bend over, so it is really important that you see a surgeon who will carefully assess your skin tone before making a final decision.
Coolsculpting is another excellent option for this area, and again an experienced technician is required, to ensure that the device will fit well and will work for you in this area.
All the best with you and your ongoing research,

Hi crazydaisyx6,
Overall you look great after your procedure. Sometimes patients get additional liposuction after a tummy tuck for additional definition and refining. You would likely benefit fro addtional liposuction if what you have under your breasts is adipose tissue (fat). A consultation with your surgeon or another board certified plastic surgeon is the best first step in addressing your concerns.
