Smow...I am so sorry for what you're going through. I do hope things improve, but.....
In 2008 after hospital consultations and with my solicitor I was told I had a case to sue the hospital over the treatment and death of my husband. I was informed of the highest payout I could expect.
I asked my solicitor if, by taking action, things would improve for others. His reply was that in his experience no.
I took no action. I have followed news items about that hospital. It's as bad as ever.
