First of all, I’m so sorry for your ‘double whammy’. You’d think that we had our fair share just having MS wouldn’t you?
Secondly, I was very close to posting the same question myself. I’m due to start radiotherapy (for breast cancer) myself this week. I too am concerned about how the fatigue will impact my MS fatigue, as it’s one of my worst symptoms…
Only one person (on another MS forum) was able to reply to me, and she said that it was exhausting and to get as much help as possible. I’ve now done my Xmas prezzie shop and I’ll be buying ‘bung in the oven’ stuff for the festive meal.
I hope that someone is able to answer your (our) question, but in the meantime, I’ll happily keep you updated if you’d like?
