aftereffects of BCG bladder treatment

Hi

Just trying to see if anyone else has had the same experience.  Recently finished my second 'maintenance' treatment after being passed 'clear' following the main 6 treatments. So really good news but the aftereffects (if thats what they are?) seem to be lasting much longer than previously.  The bladder irritation after treatment usually went after two or three days but with this last treatment l still have a constant ache in the bladder/scrotum area three weeks after treatment?  Pain is controlled by Paracetamol so not that severe but would like to hear from other sufferers to see if this eventually goes away?
