Hi @Louise64 I'm so sorry to hear you are going through this, like all of these treatments it seems hard to predict how you are going to react. I would ask to see your radiation oncologist and escalate the whole thing - as another nine treatments when you are suffering so much seems like you need some expert help.
I hope someone else can chime in here that had a similar reaction and worked out a way to cope.
Nine treatments to go! You are so close to finishing. And this will dim into the past I promise! But in the meantime I'll be thinking of you and hoping for better days. x
