Peggy,
I had three 45-minute cyberknife treatments. I felt nothing during and immediately after each. I was given a steroid medication after each session. A week later, I am now experiencing a pretty constant headache- perhaps from swelling, perhaps it's from my days in a normally noisy and chaotic classroom with forty 5 year olds with too much to do and not enough time to do it all in.
I assume you are having F.S.R.- this would be small doses of radiation spread out over 26-30 days, right? From my reading, I suspect you won't have much in the way of "aftershocks." Maybe headache. I wonder why your doctors haven't given you that info. Certainly, there is someone at the facility who can answer your questions about it. I am much like you in my need to know- don't surprise me, give me the facts, possiblities and maybes included. I know everyone is different, but armed with information is better than waiting and wondering "what's up?
?"
Hang in there and good health to you,
Terry
