Eligible individuals were divided into exacerbation and non-exacerbation groups based on the patient-reported worsening symptoms of previous chronic pain after SARS-CoV-2 infection. Baseline information, COVID-19 symptoms, laboratory parameters, characteristics of exacerbated chronic pain, quality of life, anxiety and depression levels were systematically collected.Results: Ninety-five (95/441, 21.5%) older adults suffered from exacerbated chronic pain with a median numerical rating scale (NRS) score of 6 (4– 7) on a median duration of 4.9 (4.3– 5.6) months after SARS-CoV-2 infection. More participants were not vaccinated against COVID-19 (46.5%, 40/86 vs 26.1%, 86/330, P < 0.001) in exacerbation group. Exacerbation group exhibited poor quality of life (EQ5D index: 0.734 [0.536– 0.862] vs 0.837 [0.716– 0.942], P < 0.001), more severe anxiety (GAD-7: 2 [0– 5] vs 0 [0– 3], P < 0.001) and depression (PHQ-9: 4 [2– 7] vs 2.5 [0– 5], P < 0.001) than non-exacerbation group. Risk factors significantly associated with exacerbation of pre-existing chronic pain were neuropathic pain (aOR 4.81, 95% CI 1.73– 13.32, P = 0.003), lymphocyte count (aOR 0.31, 95% CI 0.12– 0.78, P = 0.013) and D-dimer levels (aOR 6.46, 95% CI 1.92– 21.74, P = 0.003).Conclusion: Our study observed a prevalence of 21.5% exacerbation of pre-existing chronic pain after SARS-CoV-2 infection, with a consequence of poor quality of life, more severe anxiety and depression. Previous chronic neuropathic pain, lower lymphocyte count and higher D-dimer levels were risk factors associated with the development of exacerbated previous chronic pain.Keywords: post-COVID-19, older adults, chronic pain, exacerbated symptoms
