Will this bunching up go away I'm one week from breast surgery? (photos)

By "bunching up", are you referring to your incision? If so, yes, the raised end will relax with time. Be patient and kind to yourself as your body recovers. My best,

Some puckering around incision lines is due to internal sutures which often dissolve around 6 weeks post surgery leaving a much smoother appearance.  Additional smoothness is obtained when the implant or breast tissue settles into the lower pole, which may take 3-4 months.  "Dog ears" or standing cones at the very end of incisions result when tissue is tightened, leaving relatively lax tissues at the ends of incisions.  While the appearance of these often significantly improves with settling and reduction of swelling, there can be a small residual fullness.  Be patient, you will see improvements week to week.  Good luck!
