I am almost 5 months out now, I had left neck dissection and 33 rads. Don't know if this had anything to do with the radiation or not but whenever I bend my head down, I get a tingling sensation that goes the whole way down my back. Went to a massage therapist but that didn't help and she couldn't give me an explanation for the cause. Anyone else ever experienced this? Should I tell my doctor and can anything be done to stop this weird feeling?
