Methods: Using PubMed Central and Google Scholar search engines, we used as key words “muscle pain”, “joint pain”, “body ache”, “fatigue”, in Covid-19 patients. Results: After screening, a total of 76 articles were included following inclusion criteria dated between January 1 and July 1, 2020. All articles were published in English comprising 36558 COVID-19 cases. In cross sectional studies, fatigue was found in 55%, myalgia in 26%, and arthralgia in 20%, respectively. In cohort studies, fatigue was found in 35%, myalgia in 15%, and arthralgia in 5%, respectively. Sporadic case reports also mention back pain, bone pain, myositis and arthritis as presenting symptoms of COVID-19.
Discussion: Fatigue was the most frequent musculoskeletal (MSK) manifestion of COVID-19 followed by myalgia and joint pain. The frequency of the different MSK manifestations in COVID-19 may vary widely among different geographic regions.
Conclusions: MSK like fatigue, myalgia and arthralgia are frequent symptoms in COVID-19 patients and may vary in different countries.
