Case of shingles in cancer patient

Had a case of band like burning pain with no noted lesions by a cancer patient.

The oncologist insisted that patient had some local recurrence though her blood tests were perfectly normal except for lowish white blood counts.
Hence she was treated for shingles with low dose lambda, epstein barr, CMV and thuja. In 3 days all the pain subsided and she refused the repeated CT scan.
Tq Dr tariq for knowledge that stopped an unnecessary CT scan.

Note : several shingles cases dont have lesions just the burning pain in the dermatome
