Arm pain, a common complaint, stems from various causes. Muscle strain, overuse, or injuries often lead to discomfort. Conditions like tennis elbow, carpal tunnel syndrome, or rotator cuff injuries can result in pain. Nerve compression, arthritis, or heart-related issues contribute too. Proper diagnosis requires understanding pain characteristics, location, and triggers. Medical history, physical examination, and sometimes imaging or tests aid assessment. Treatment ranges from rest, exercises, and physical therapy to medications or surgical interventions when necessary. Timely attention to arm pain ensures improved mobility, functionality, and overall well-being, facilitating unhindered daily activities.
