Sorry to hear the news and diagnosis. Similar but different situation for me with my situation above. For me, chemo was added for 6 weeks of radiation and I'm going to maintenance plan of 5 days on, 23 days off. I do have slight blurry vision in my right eye, noticed after treatment one and it did get a little worse. Vision is manageable but different. I did not have any mobility issues. I did experience slight fatigue in the later weeks, frustrated easier, some anxiety, brain fog, and sleeping challenges. Most of this persists 3 weeks after radiation ended. I should exercise more so kudos to her!
