Causes of Elbow Pain. Elbow pain is sometimes due to arthritis, but in general, most elbow pain results from overuse injuries. Sports or any activities and professions that require repetitive hand, wrist or arm movements are more prone to elbow injury. Common causes of elbow pain are bursitis, elbow strains, and arthritis.
Several diseases can also cause elbow pain, though itâs usually not the main symptom. Arthritis: Many types of arthritis can affect your elbow, but the main ones are rheumatoid arthritis and osteoarthritis. Rheumatoid arthritis is the most common type of arthritis in the elbow. When you have it, your immune system attacks your bodyâs healthy tissue and causes swelling in your joints. You get osteoarthritis when your elbow cartilage breaks down over time, which means the bones rub together and cause pain and stiffness.
