Cindy,
my RO warned me about "texturing" in the neck muscles as a result of the radiation and I didn't really understand what that meant but recently, at times, it feels like something is trying to twist my neck, this accompanied with a headache. I just had an MRI and it all looked good (except for the "usual" stuff like spondylosis (aka osteoarthritus - common in my age group), so I don't think that there are any other physiological reasons for this. I just pop a valium and a Vicodin and it goes away. Just to be safe though I would mention the headache issues to the MO.

"Chemo brain" - that took a while before I could put together whole sentences ;-) Three years post Tx my memory is back to normal now.
