"Post surgery treatment"

I was a patient for 4 days on a surgical ward (11 ). On admission, all the staff was very welcoming I was made comfortable. On the second day I had surgery and was bought back to the ward. While waiting for the spinal to wear off I was very happy I had the surgery.

As the feeling in my lower half started coming back I started feeling a terrible pain in my bladder area. I told the staff and I was told it could be retention, a bladder  scan was done and I had more than 900mls. The pain started getting worse, I tried to explain to the staff the pain was now radiating to the back area where I had surgery it was unbearable pain. I was told to relax it was retention. At this time the pain I was going through can't be explained,  I was offered 2 paracetamol, and I was told that's all that was prescribed. I told the staff that I was told by the surgeon and the anaesthetist that after surgery I'll be in a lot of pain and I'll have morphine prescribed when needed. They still told me that's all that's prescribed. I know I'm not the first to have the procedure I had ( Hemorriodectomy), why wasn't it checked when I came back to the ward that the right analgesia was prescribed to prevent me suffering unnecessarily. 

After suffering unbearable pain I asked them how can they not know the after effects of the surgery, all they could say to me was that I should pick it up with the doctors the following day. Which I thought was a shameful response. If you work in a certain department you will know what happens following procedures. 

Please don't class this as a complaint because a was treated very well, but after having procedures, a patient depends on the staff to be their advocate, not tell them to take it up with the doctors themselves. That staff member's bedside manner is an embarrassment to the ward. I hope no one else has to go through what I went through.
