"New knee replacement,"

I had my knee replacement in January 2016, after operation I was not given pain relief only offered paracetamol and nurofen. I was told that after I came out of operation I should have been given pain relief immediately, by the time the pain was so bad I was given liquid morfeen but was sick straight away. I was then given morfeen capsules every 12 hours but had to ask every time for them and as staff were always busy didn't sometimes get them. I couldn't get out of bed because the pain was that extreme I passed out, no extra pain relief day four out of bed physios said I passed all necessary things so go home absolutely traumatic time for me.
