Proportional distribution of 2657 patient visits based on subjective and objective pain levels (no, mild, moderate, and severe) in 2019, 2020, and 2021. Self-reported pain, pain on percussion, and pain on palpation. The illustrations show how the proportion of moderate (purple) and severe (red) pain dramatically increased during the initial outbreak of COVID-19 in 2020. Although in 2021 the subjective pain levels (pain on percussion and palpation) returned to the norms of 2019, self-reported pain remained significantly higher than 2019. See Tables 2, 3, 5, and 6 for the details of the statistical analyses.
