Recently completed 9th treatment. Definitely getting more painfull with each session, particularly in hours 4 -7 after "injection". Treatment itself no problem, just the after effect that afternoon and early evening. Awaiting appointment for next cystoscopy/biopsy. The problem I have is the apparently permanent bladder irritation at night, that means I still get up 3 - 5 times a night to relieve myself. or just walk round the house. During the day no real problem; unless I sit down too long and fall asleep ;-)
