My left breast is healing faster than my right. Is this normal?

Yes it's perfectly normal for this to occur based upon the limited photos you have submitted. See your plastic surgeon who can give you the best advice. Good luck!

The first question is how different were they before getting implants?  The difference you see now could be a reflection to your BI (before implant) condition.  Also, which arm is dominant?  Some people will stay swollen longer on their dominant side due to more use, while others have the opposite.....using that side more milks the swelling out faster.  There could be some fluid accumulating on the right.  Doesn't look like blood, since you don't really have bruising.  I would guess you have a 1-week followup appointment, so you should get some answers then.  If you do not have an appointment.....make one!  Good luck!

You had two different operations, right and left, and it would not be expected that they heal at exactly the same rate or with exactly the same look. Your final look will be a reflection of the asymmetry you had prior to augmentation. 

In general, it's common for one side to heal differently, and at a different pace, than the other.  Even once the healing process is complete, the two sides (of any procedure) rarely look exactly the same.  So from the standpoint it's not necessarily a concern that they look a little different (although I'm not sure what you mean by "I did not remove my implants" - did you have them replaced with smaller ones)?Also in general, and certainly with concerns such as the one you have, you should contact your own plastic surgeon and arrange to be seen in person if indicated.I hope that this helps and good luck,Dr. Alan EnglerMember of #RealSelf500
