The research methodology applied consisted of diagnostic survey method, and as the technique, a survey of our own design was used. The VAS Pain Scale was used. Statistical analysis was prepared in the program SPSS20. The statistical significance of differences was determined at a confidence level of p<0.05. Results. 98.7% of the surveyed nurses complain about back pain. The biggest group consisted of those with very severe pain (47.4%). At the same time in 80.26% of cases the pain was located in the lumbosacral section. Multiple comparisons showed that the level of pain intensity was higher in those working on the contract than in the personnel working on the basis of a contract of employment (p=0.045). The analysis showed no statistically significant differences in the level of pain intensity between respondents in different workplaces: Chi2 (2)=3.69; p=0.158. Conclusions.
