You are right to discuss this with your doctor...that is the first place to go for answers. BUT I will tell you that fatigue is the most common side effect of BCG treatments. It does go away eventually,

Was dx'd in late Jan, surgery early Feb, finished 6 weeks of BCG mid-April. I was feeling great and now the last few days I have the "cancer tired" feeling. My tumor was T1 no metastasis - awaiting follow up cysto in about 2 weeks. Has anyone had this feeling of utter exhaustion post surgery and tx? I working full time and resumed my normal life, nothing crazy. So I am stumped. I have a call into the doctor but thought maybe some of you might have insight.
