I have been experiencing a strange squeaking sound in one of my breast implants and it's extremely annoying ... like fingers across a blackboard. I can also feel the sensation of the implant rubbing on the rib or bone. It started at week 7 which concerns me because what I have been reading is that it's normal for early post op but this is 7 weeks later. It's been going on for about three weeks and does not seem to be getting any better. I can also feel the implant shift when I bend forward and that, too, started at the same time. I have been wearing firm support in the daytime and a sports bra at night. I am beginning to think that maybe the sports bra is causing an issue because it holds me very firmly and could it possibly be pushing on the implant to stop any pocket formation? I am curious as to how a pocket forms around a breast ... what will help it. If a pocket forms, wouldn't the rubbing stop because there will be a cushion between? Will a revision surgery help fix the problem? I am beginning to regret getting the implants. Although my ps doesn't seem concerned because it can't cause any harm, I am not happy with the squeaking sound. Thanks.
