"Shocked"

I was admitted on a Wednesday afternoon with abdominal pains to SAU, their I was told I had kidney stones so I would be put on a ward and have a scan the next day. Thursday morning I see a different doctor who tells me it's my appendix but will have scan I'm now nil by month 9am. Asking nurses all day about scan they don't know. 6pm I see consultant who says can you sign form for appendix removal so I sign form and tells me op will be soon. 8.30pm 11 half hours no food or drink I get taken down to surgery. Half 12 I wake in recovery to go back to ward very sore. Next day consultant comes and tells me no appendix removed, It was my tube that was a little swollen so operation for nothing if they would of scanned me. Friday night less then 24hours after op I get sent home No painkillers (I was on morphine). Saturday morning I wake up then the pain starts so bad I get rushed back in by ambulance nurse is shocked why did dr send me home. Back on ward to stay for another 3 days get discharged Wednesday. I'm still in pain for an operation I didn't need tried finding out why and I get blame this dr or that dr. So angry and upset the way I've been treated. Also the dr who discharged me was even shocked I had surgery and didn't need it says it all
