Material and Methods
This study was conducted retrospectively. Data of patients diagnosed with shingles between June 2017 and July 2020 were analyzed. Patients who did not have shingles and who applied to family medicine because of general control were accepted as the control group. The localizations of the lesions (head and neck, thoracic, lumbosacral, extremities) of the patients with shingles, the presence of subjective symptoms (pain, itching), and vitamin B 12 values of both the control and study groups were recorded. Patients who took vitamin supplements, breastfeeding and pregnant women, children in growth and development age, those with central and peripheral neurological diseases, those with symptoms both pain and itching, and those using opioids and non-opioid analgesics were excluded from the study.
The SPSS 21.0 program was used for data analysis. Frequency (n), percentage (%), mean ± standard deviation values were used as descriptive statistics to evaluate the data obtained from the study. Relationships between numerical data were evaluated using Student’s t test for independent samples when normality assumptions were provided, and nonparametric equivalents of the same tests in cases where normality were not be achieved. Relationships between categorical variables were determined using the Chi‐square test. The P value <.05 was considered statistically significant.
