On the 4th Aug I had robotic surgery to remove prostate but 4 days after the catheter had been in had awful discomfort when I sat down (presumably from the tube in the urethra). 2 days after it was removed I had a terrible infection and spent another 3 days in hospital and within days found that this discomfort returned always after sitting down for any length of time. It feels like the urethra is being squashed up while sitting. Doing pelvic floor exercises seems to make worse. Has anyone else had this problem and how long does it last ???.
