Hi Kazza
good luck for Thursday. I had a lumpectomy where they removed 3 tumours as well as the sentinel node. I didn't have drainage either. I was more uncomfortable that painful. I went home the same day as the surgery. I have chemo first (TCH) which started 3 weeks after surgery. I started radio 3 weeks after finishing chemo.
As far as the fog is concerned, I had to (and still do) write everything down. Your head is so full of everything you have to know and your appointments and thinking about what's happening that there isn't enough room in your brain for the day to day mundane stuff. Chemo added to this with chemo fog as well. Add to that the shock of what's happening and it's not surprising that we forget stuff.
hang in there. You will get through this. Karen xox
