Study Design: Retrospective study.
Objectives: The purpose of this study was to identify the characteristics of low back pain as a unique symptom of the Omicron variant of COVID-19, distinct from respiratory symptoms.
Summary of Literature Review: The common symptoms of patients infected with COVID-19 are fever, cough, and fatigue. However, it has been found that back pain can worsen in these patients.
Materials and Methods: We enrolled a total of 2,443 patients who were hospitalized for the treatment of infection with the Omicron variant of COVID-19, including 1,509 patients in the first outbreak (from January to June 2022) as Group 1 and 934 patients in the second outbreak (from July to December 2022) as Group 2. Our primary outcome was back pain in patients who visited our hospital after a positive polymerase chain reaction test.
Results: Respiratory symptoms were present in 2,168 patients (88.74%), fever in 1,261 (51.62%), headache in 814 (33.32%), low back pain in 733 (30.00%), and loss of taste or smell in 223 (9.13%). Outdoor activity had decreased due to the government’s social distancing policy in 947 patients (62.76%) in Group 1 and 571 patients (61.13%) in Group 2. There was a positive correlation between low back pain and decreased outdoor activity (r=0.317, p=0.001).
Conclusions: There was low back pain in 30.00% of patients as a unique symptom of the Omicron COVID-19 variant. Back pain was positively correlated with decreased outdoor activity, and treatment of infection with the Omicron variant improved low back pain in most cases.
