I Have Recently Had My Second TURP Plus I Had

I have recently had my second TURP plus I had bladder stones layered, all after being characterised for months. When the catheter was removed the day after the operation, my flow was great but then it declined even though it was still acceptable. Well it would be after not having to think for itself for 16
months. Unfortunately I may have picked up a bug and now I need to void every 15 minutes and the pain is quite intense. Help---please
