Hi, my OVER the muscle silicone implants, mammary fold incision, are 3.5 years old. The right nipple is VERY itchy. It actually wakes me up from sleeping. It has been happening for several months now. What could the cause be? The scar tissue on this side is attached to the muscle (I know this because when I flex my right pectoral the implant rises upwards.) Can I request a breast scan from the NHS to check everything is ok? My surgery was private. How much is a private scan?
