You will hear noises coming from your breasts. That is normal. The implants are just settling in. And no they are not leaking, you will notice a dramatic change in size if they are saline implants.
You will have a pinched nerve that hurts like hell on your breasts! That is normal since an implant can sit on a nerve, so every time you move it will hurt. But fear not, that pain will go away quickly once the implants settles in.
These little twinges should slowing disappear and/or get less noticeable over time. They should not get worse. The healing process for breast surgery does take time.
Good luck and thank you for your question.
