Suprapubic Catherer

I have had the catherer surgery in November 2017. The surgery and recovery has been without any problems. I have been changing the catheter at monthly intervals with no problems. The only problem I am encountering is I have sporadic pain in my penis. I have this sensation like I need to urinate but no discharge. There is a feeling like a spasm is occurring it seems to occur when i am emptying the leg bag or night bag. Sometimes when I am showering this pain occurs too. Did any one in the forum experienced similar sensation and if so what was done to get over it. Thanks. 

Bladder spasm.     How are you doing now?
