Hi, My side effects with maintenance have been similar, and the first 24 hours or so following instillation I have felt pretty rough, but usually before the next treatment , the main urinary symptoms have cleared, including passing blood and clots or debris. I think it is important that the pain,bleeding, cramps etc have cleared before another dose is given, but it may be worth speaking again to your doctor about possibly reducing the dosage. I believe research has shown that the treatment is still effective, even at considerably reduced concentration.I found that as regards drinking, every time I had been to the bathroom, I would drink a glass of wáter at least- failure to do so resulted in more pain, and particularly painful urination.Whilst I am not a doctor, I would think the "skin stuff" is some of the tissue lining the bladder being sloughed off by the body·s defence system as it reacts to the bcg.
