Nearly finished radiation!

Hi ladies and gents, well, I finished radiation nearly 4 weeks ago. Breast pain and skin all cleared up nicely, and I didn’t really get that tired - until now! In the last week I’ve had headaches and really sore neck and shoulders, and I’ll get these sudden waves of brain tiredness where I feel like I can’t think anymore and need a lie down. (Lucky we are in lockdown so I can!) . I do kind of wake up tired.

is this the fatigue they talk about? I was expecting it to end about now not start! What have your experiences been after radiation finished?
