I had a catheter in for 3 days after a Green Light Laser. It was absolute torture and I felt it and thought about it constantly.
But the two week stretch after robotic surgery was a breeze - didn’t even feel it; but maybe that was because the rest of me felt like I had gone 15 rounds with Smokin Joe Frazier.
Try to walk on a treadmill or outside weather permitting. You can really do many light activities after surgery as long as you don’t strain or overdo it. It will take your mind off of the catheter quite a bit.
