Breast Implant Sliding While Lying on Back

Implants will move when you lie on your back. Your implants are not very large so I wouldn't expect them to move that much but just like real breasts implants cannot defy gravity. So depending on the shape of your ribs they may move a little laterally or up towards you armpit. The side that doesn't move as much is the one that probably has a little bit more of a capsule around it which is preventing it from moving as much.

This is normal. Your skin is stretching and the implants will move and settle. They are small implants so they will be more mobile sooner. I would follow up with your plastic surgeon. I recommend that my patients wear a sports bra for six weeks after surgery that does not dig into the incision. You are way too early to massage the implants and I would stop doing so.

Good Luck,

The likely explanation for this problem is that the pocket for the implant has opened up in that direction.  This is more likely if the implants are under the muscle.  If early enough (within six weeks from the surgery) the problem can be fixed by wearing a tube top that compresses you on the sides preventing the implant from sliding out.  Hopefully, with this, that space on the side will scar down and the implant will stay put where you want it.
