I am recovering from stage 4 tonsil tumor, had surgery in Nov, 02 and radiation treatments, I too have felt this electrical charge, and also experience tingling in my hands. Did not know these were side effects of treatment. Isn't it wonderful how forewarned we are? Its been a learn as I go along experience, for sure,as so many issues were not discussed, but perhaps if they were, I would have declined treatment. I am happy to read that these feelings do go away in time. Thanks all for sharing!
