I have undergone this treatment.Five days per week,for seven weeks.The side effects,unimaginable pain,I can only now describe-eight weeks later.On each side of my tounge the radiation Burned stips out.Each taste bub became like a razor-blade cutting my tounge,every second of every hour of every day.Even with a Fentenol patch, and many Vicodin, the pain was unbearable.My sense of taste is not gone it's ruined.Everything tastes like chemicals.I have lost 70 lbs., @ 6 ft. I am 144 lbs. and losing!
