2 Years Post Op and Bladder Aches

cf

Just curious to see if anybody has experienced what I have been experiencing.  I am 2 years 3 months post op after a radical prostatectomy.  Everything is good except recently my bladder has started to ache deep down.  These are short experiences - maybe a few seconds to +/- 30 seconds. I am trying to identify the exact things I have been doing when the aching starts up.  At this point it looks like when I stand after sitting for a good while - working in front of a computer.  I will say that I have had some aching off and on since the surgery.  Just interested to know if this is normal or do most people not have that symptom.
