I had Cyberknife done end of Mar.08,In jun.started having spasms,half my face would contort,for about a minute or two.Dr.felt it was from radiation affecting cranial nerve.took decadron for 1mo.as soon as i tapered(last week).the spasms came back with a vengeance5 to 6 times daily.Back on decadron but for a shorter time as i have had a lot of steroids in last year,also just started neurontin,which I already don't like,makes me tired.I am still getting spasms,but have only been on meds for couple days.
My understanding is that this is relatively uncommon following cyberknife,but theres always these odd things that can happen.These spasms are more embarassing,than anything,not painful,but the whole side of the face scrunchs up.Mine did star out with some twitching around my eye,progressed around my mouth,feels like worms under my skin.I hope yours gets better and doesn't progress.
