"Kidney and bowel op awaiting for"

For the 2nd time since 1st surgery I have been brought in with a kidney infection. Again I'm being sent home, more antibiotics and a wait again for surgery to remove kidney and part of bowel. How many times will it take before they operate. I'm waiting to see the doctor who will do the surgery and still waiting to get an op date. I'm just in so much pain all the time. They send me home with the same meds that no longer work. I am slowly losing any confidence in the NHS. Just a joke. Waited 2 year for 1st op. God knows what I'm waiting for this time for this op. All time acquiring one infection after another, one hospital stay after another. Just a nightmare. I'm fighting to get a painkiller that does work. Think I am hitting my head off of a brick wall. Just had enough.
