M75: Shoulder lesions

Shoulder lesions refer to a variety of conditions or injuries that occur within the shoulder joint and associated muscles, ligaments, or tendons. Causes can be diverse, ranging from degenerative changes due to age, overuse injuries often seen in athletes or manual laborers, to accident-related trauma. Common symptoms across these conditions include pain, stiffness, and limited range of motion, which might worsen during physical activity or at night. Progression of these conditions varies but can lead to more serious complications if left untreated. Some individuals might experience continuous pain, while others might have intermittent bouts of discomfort. These lesions primarily affect the musculoskeletal system and can significantly impact a patient's quality of life by limiting their ability to use the affected arm or shoulder.
