The study was registered in the Clinical Trial Registry of India (CTRI number: CTRI\/2022\/07\/044336) Patients aged 18\u201365 years attending the post-COVID clinic with musculoskeletal manifestations were included. Patients\u2019 demographics, personal habits, and clinical history specific to the course of COVID-19 were collected and a physical examination was performed. Blood samples were collected to assess iron, selenium, zinc, and copper, and complete blood picture with differential count and C-reactive protein (CRP) assay. Musculoskeletal manifestations during the post-COVID phase (within a year after the COVID-19 infection) such as fatigue, myalgia, arthralgia, myositis, fibromyalgia, and arthralgia were documented. Copper and zinc levels were analysed at the National Institute of Nutrition and all other parameters were analysed in our institute.
