Hey liliana day 2 already! Check the skin where its hurting. I used to cream my boob but forget the actual nipple and it started hurting. Everyone reacts differently so maybe mention it to the medics.
I'm afraid the tiredness has never gone away for me and I'm 17 months post treatment. Take it easy and rest as much as you need to but I always made sure I went out for a walk every day. I had read that a bit of exercise helps battle the fatigue. Don't know if it helped but I tried everything!
Hope all you ladies are rocking on and enjoying your evening as best as poss.
