When I asked my radiation oncologist about feeling that funny shocking feeling when I look down, especially while out walking, he turned to the young doctor in training who was trailing him, and asked, " that is called .........."? In other words it is a common syndrome, whose name I don't recall. I do think that it is supposed to subside after a while. Of all the sid effects of radiation therapy, it is probably the most innocuous for me.
