Women across the UK are suffering after an operation they were told would transform their lives. Instead, some of them say their lives have been ruined. For years women have been fitted with mesh-like devicesto treat prolapse or incontinence - often caused by childbirth. Although it's been a successful treatment for many of them, thousands of women in the US, the UK and Australia are now suing, after finding themselves in agony or suffering other serious complications. Reporter Lucy Adams meets women living with constant pain. She investigates how and why these devices were approved for use in the first place and asks whether manufacturers and regulators should have acted sooner to take some of them off the market.
