My left breast looks round and full on bottom. Should I massage the smaller breast so it can drop and look fuller?

At 5 weeks after surgery your breasts are still settling. This takes about 3-4 months to occur, and so it would be better to wait until then before assessing your results. I don't routinely recommend massage, therefore it's a good idea to ask your surgeon if it's okay to massage your breasts. 

You are still early in the healing process, from your photos your breasts look great. Each plastic surgeon has their own post operative instructions. You should follow what your PS says.

Hello,It is still very early in your recovery, and there is nothing that suggests a problem from the photos you provided.In general, it is a mantra of on-line surgeons like myself to tell patients to 'follow your surgeon closely'. However, when it comes to implant massage, I feel confident in telling you that you don't need to do it. There is no scientific evidence to suggest that implant massage has any positive effect on your outcome, nor does it prevent or treat capsular contracture.  Conversely, there has been one recent paper published that followed busy breast surgeons, and it found a correlation of higher rates of capsular contracture in patients that did breast massage.  A cause and effect relationship was not established however, but that should give we surgeons some pause before we mindlessly tell our patients to massage their implants.You look fine, and I think you should have good symmetry in the end!Best of luck!
