Experts believe that muscle ache is a common symptom in case of viral infection and coronavirus is no exception. But the rise in cases of body pain can be due to multiple factors. It can be due to inflammatory mediators or maybe the mutant variant is affecting the musculoskeletal system more than the previous variant. When the virus affects the musculoskeletal system, it commonly affects muscles, bones, joints, and ligaments, leading to aches and pains. Even though body ache is so common in case of the Omicron variant, it is not considered as the top five symptoms of viral infection. Runny nose, headache, fatigue, sneezing, and sore throat are initial symptoms of Omicron you must look out for.
