I just had my surgery a little over 2 weeks ago now. I was in excruciating pain upon waking up, where they gave me a PCA pump that gave me 1ml of morphine mixed in saline every 3 minutes when I hit the button. It wasn't until I started making a commotion that they called the doctor. Have they been giving you medication via PCA pump and if so, do they also have a dose of medicine for the pain that is used for breakthrough? When it came to bladder control, I had the catheter in for about 2 days, and even had to go through a bladder scan because I was on normal saline with the bags being changed every 6 hours, but they also hit me with 4 boluses of saline, the volume I cannot remember but it was up there, and each bolus was administered in 1 hour intervals. The colon and bladder are late to start up due to the sheer amount of drugs they hit you with.
If possible, try and walk once they give you something for pain breakthrough, and if you are going to raise the head of the bed or sit up to the side of the bed, hold a pillow firmly on your abdomen. The added pressure and cushion of the pillow is a huge relief.
