"How did a normal pregnancy end in disability?"

I was a nurse and loved it. However when I became a patient and I feel that was mistreated, and I now have to live with the devastating effects. I have been left permanently disabled. I am in pain constantly and it seems they just don't care. I feel that what happen has been covered up and no one will explain why I can't walk any more. It all started with a normal pregnancy and ended in disability.

All I want is for them to explain why I was healthy and pregnant, and why I can't walk now and have constant excruciating pain.

When speaking to staff at another hospital, they have said that I should have been treated earlier and I would be fine now, but the Royal Gwent just ignore this. I can't afford the legal help that I need to move this on, but I need answers.
