"Cancelled operation twice"

Hello,

I am at my wits end as well as severe pain.

In 2016 I had a knee replacement, after the operation the pain was worse than before I had replacement, I kept going back to hospital complaining of pain, I was told this was normal, at the end of the year I was told I would have to wait for bone scan. After eventually getting bone scan I was told I had a infection in the bone and I would be transferred to another consultant. Over the last few years I have been left in so much pain, in fact on 1 of my hospital appointments I was told by 1 of consultants understudies that I was being discharged.

I last saw consultant June 2018 and they agreed that they would do corrective surgery in the autumn of that year, I waited and waited eventually I was given a date in Feb 2019, this was cancelled, I was given another appointment  in March  even had pre -op tests but surprise surprise I got another letter cancelling the op, how long do I have to wait anyone help please.

Thank you
