Usually the effects of radiation, redness, start between 10-14 days after starting, but some may have them sooner. Did they tell you to use cream on your neck? Usually it's Aquaphor, last year Cetaphil was also recommended to me, less gready, but don't use the creams before your radiation treatment. They have audio, and CCTV to monitor you, but I often thought the same, but thought no plastic mask was going to hold me down lol. Good luck the rest of the week.
