Idabob its not unusual to feel fatigue early on, for all the reasons kooksadream said. I had radiotherapy 2011 at first diagnosis, and it does accumulate. I worked full time right through, but radiologist made me have 2 weeks off at the end. Im so glad I listened, I wasnt ready for the extreme fatigue that hit then, it was indescribable, plus had severe burn, but with solugel healed within a week. Just be gentle with yourself, and nurture you every step of the way, nothing and nobody is more important than you through this. Hugs Melinda xo
