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
