I really sympathise with your plight. I have nerve damage in my abdomen after surgery carried out at priivate hospital 3 years ago and am still suffering considerable pain, also got compressed femoral nerve in my leg from this. Nobody told me that nerve damage was possible infact was not told of any effects that might happen from the surgery. After fighting with the private hospital for well over a year after the surgery they agreed to re-open the wound and it was stitched in different way, which did help with the pain. But now have monthly infusions at pain clinic to try and help with the pain. Unfortunately I had to sign a form prior to the 2nd surgery exempting the hospital from any future claim. I have lost thousands due to this, which is really why I am in the financial mess I am in now. Could not work for 2 years and now work as home carer but have to deal with the pain the best I can. I really know what you are going through, if I had not signed that form then I would certainly sue for loss of earnings if that was possible.
