I've just had the 2nd infusion (3 course) on Tuesday this week, but since then I seem to have gone down hill v quickly with possible side effects. I have had terrible stomach problems (stomach pain, gas, diah) and now feel totally dehyrdrated and needless to say 'fatigue' doesn't seem to be strong enough word! I am having a gastro consult next week as the stomach problem seems to be getting worse - may need to have a colonoscopy as scans, etc don't show anything. My fingers also don't want to do what they are told! Anyone else have similar problems?
