First time on.  Prior to treatment I didn't have headaches.  Had FSR 25 treatments in nov-dec of 2005.   Have had mild headaches daily since day one of radiation.  I am more concerned about the movement I get in the back of my head which I will call brainwaves.  It feels like waves of water or a worm moving in the back of my head.  It happens when I'm on the brink of falling asleep.  I get chills in my body and head right before the movement most times, but not always.  The Dr's seem to think it is positional and neck related.  I have had neck problems for 20 yrs and never had this movement in my head.  Plus I can lie in bed for hrs and it doesn't happen until the moment I'm falling asleep. This movement started day one of radiation. I had an eeg and it was negative.  Clonazepam helps but I only take it before bedtime in the evening.  If I take a nap , I don't take the clonazepam     and the movement is worse.  I do get pins and needles feeling in my head on the an side, but that is different.  Please if anyone has had this wave movement I feel please respond.                                                                                                                                                                                                                                                                                               mema
