This study investigated the prevalence of long-term musculoskeletal post-COVID pain and their risk factors in a large cohort of COVID-19 survivors. A multicenter cohort study including patients hospitalised due to COVID-19 in five hospitals of Madrid (Spain) during the first wave of the pandemic was conducted. Hospitalisation and clinical data were collected from medical records. Patients were scheduled for a telephone interview after hospital discharge for collecting data about the musculoskeletal post-COVID pain. Anxiety/depressive levels and sleep quality were likewise assessed. From 2,000 patients recruited, a total of 1,969 (46.4% women, age: 61, SD: 16 years) were assessed on average at 8.4 (SD 1.5) months after discharge. At the time of the study, 887 (45% women) reported musculoskeletal post-COVID pain. According to the presence of previous pain symptoms, the prevalence of "de novo" (new-onset) musculoskeletal post-COVID pain was 74.9%, whereas 25.1% experienced an increase of previous symptoms (exacerbated COVID-related pain). Female gender (OR1.349, 95%CI 1.059-1.720), previous history of musculoskeletal pain (OR1.553, 95%CI 1.271-1.898), the presence of myalgia (OR1.546, 95%CI 1.155-2.070) and headache (1.866, 95%CI 1.349-2.580) as COVID-19 associated onset symptoms, and days at hospital (OR1.013, 95%CI 1.004-1.022) were risk factors associated musculoskeletal post-COVID pain. In conclusion, musculoskeletal post-COVID pain is present in 45.1% of COVID-19 survivors at eight months after hospital discharge with most patients developing "de novo" post-COVID pain. Female gender, history of musculoskeletal pain, presence of myalgias and headache as COVID-19 symptoms at the acute phase, and days at hospital were risk factors associated with musculoskeletal post-COVID pain.
