Navigating the Diagnostic Maze: A Case of Post-COVID-19 Tenosynovitis.

Post-COVID-19 sequelae can include various complications, including musculoskeletal manifestations. Unvaccinated against COVID-19, a 21-year-old woman initially experienced severe COVID-19 and subsequently recovered. She later developed mild COVID-19, which was followed by severe myalgia and joint pain in her upper extremities. After a third COVID-19 infection, she experienced intense pain in multiple hand joints and lethargy. The blood tests were normal, and the ultrasound report revealed tenosynovitis of the wrist joint. Her pain improved with combined treatment approaches.  To our knowledge, this is the first case report of post-COVID-19 tenosynovitis. We have also highlighted the predisposing factors for the development of tenosynovitis, which may include being unvaccinated and lifestyle changes, such as a sedentary routine. This case also emphasizes the need for further research into the long-term effects of the condition on mobility and quality of life.
