“We’ve realized that the COVID virus can set off the physique to assault itself in numerous methods, which can result in rheumatological points that require lifelong administration,” corresponding creator Dr. Swati Deshmukh stated in a launch.

The examine, which was printed Wednesday within the journal Skeletal Radiology, confirmed that imaging by way of CT scans, MRIs and ultrasounds might help clarify why some sufferers endure from “extended musculoskeletal signs” after contracting the virus.

“Many sufferers with COVID-related musculoskeletal issues recuperate, however for some people, their signs turn out to be severe, are deeply regarding to the affected person or impression their high quality of life, which leads them to hunt medical consideration and imaging,” Deshmukh, an assistant professor of musculoskeletal radiology at Northwestern University Feinberg School of Medicine and a Northwestern Medicine musculoskeletal radiologist, stated. “That imaging permits us to see if COVID-related muscle and joint ache, for instance, are usually not simply physique aches just like what we see from the flu — however one thing extra insidious.” 

In some circumstances, the imaging may even counsel a affected person has had COVID-19, however in any other case didn’t know that they had it, the examine revealed.
