M62.6: Muscle strain

Muscle strain, also known as pulled muscle, is a condition characterized by damage to a muscle or its attaching tendons. This typically occurs when the muscle is overstretched or torn. It can result from many activities such as heavy lifting, during sports, or even from sudden movements or falls. Symptoms of a muscle strain can vary dramatically based on severity, but often include pain at rest and during activity, muscle weakness, swelling, bruising, and limited flexibility. In more severe cases, it might present as a palpable defect or gap at the site of the muscle tear. This condition affects the musculoskeletal system, specifically the involved muscle or tendon and its function. The progression of a muscle strain can range from a minor, isolated incident that heals on its own over time, to a recurrent issue, or in more serious cases, a significant injury requiring medical intervention.
