KathleenMary - I did have a very unusual acute reaction to GK. I stayed in bed all afternoon the day of GK. That evening, I swam with my family in the hotel pool. The following day I felt good, and my daughter and I went shopping. I started to feel some waves of dizziness, but we went out for dinner. That evening, I developed an extremely bad headache, lost all hearing in the AN ear, and literally fell over while walking through the room. I called the hospital and was put on steroids. I flew home the next week, and was too unstable to walk so I was in a wheelchair, which was weird. After taking steroids for one week, all problems resolved.
I recounted this because you asked, but again, I'll say that this was a very rare event. Most people do not have this type of reaction, and I have no idea why I did. My balance problems increased post radiation, but after months of vestibular rehab, I'm greatly improved. I'm hoping there will be no more problems like that. It was scary.
