I have recently had surgery for excision of a urethral diverticulum, and have an indwelling catheter ( for 2 weeks only). When i empty the catheter (dont have a bag, its a valve) the catheter judders and its sore. Also i now have a feeling of frequency and a sharp pain in my bladder when emptying the catheter. I dont know if the is just part of the healing process as i only had surgey three days ago, or should I be contacting the hospital? I am already on oral abs.
