Is It Normal for Silicone Implants to Move when Massaged?

Thank you for the question.

Some movement of the breast implant with massage should be expected. Generally, plastic surgeons will develop a “pocket” for the breast implant;  the pocket may be slightly larger than the breast implant to allow for some movement (not stuck on or fixed look).

Too much movement  of the implant however can be problematic and a sign of implant  displacement;  in person examination by your plastic surgeon will be helpful.

Best wishes.

If you are starting to
experience movement of one or both implants and pain in your breast and your
arm, perhaps the implant(s) has/have become displaced.  Sometimes displacement of a breast implant
can impinge upon nerves in the chest or near the armpit, and this can be the
source of new-onset pain.  You need an
evaluation by your plastic surgeon to determine the cause of these new
symptoms.  If a breast implant has indeed
shifted position, surgical modification of the breast pocket can correct the
problem. 

Some implant movement is expected and normal, too much may mean the pocket is too large.  If it does not move at all then you worry about a capsular contracture.
