Jemima Williams from Barry said she has been living with chronic pain from mesh implants for more than 20 years.
The 63-year-old had mesh inserted in 2002 after a pelvic organ prolapse.
She said she has had countless operations since and surgeons have told her it would be too dangerous to remove any more mesh.
“There are women out there who have lost everything, their homes, their marriages, their children, she said.
“These are lifelong injuries, after 22 years I am still going through it.”
The grandmother said she was now registered as disabled and “suffering from intractable pain and intimate personal difficulties”.
The campaigner said patients in Wales needed someone to “stand with us and help fight for us”.
“The ordinary woman, going through all these injuries, suffering horrific pain, can’t get their head around fighting for redress for themselves, it is impossible,” she said.
