I guess we are the lucky winners of two simultaneous skin issues: Radiation dermatitis, which is common just unexpected that is it happening so far out of the primary treatment area, and an outbreak of shingles at the same time in a different area of the neck. Started meds. He has had shingles before and the vaccine so they said to expect a less severe case. We were relieved and caught the shingles in the window when meds are most effective.
