Swelling of the elbow is mainly due to inflammatory processes. Excessive fluid collects in the tissue spaces and any cavities in the elbow and causes soft swelling of the area. Sometimes it can involve the bone â bony swelling â although the bone is in most cases resistant to the inflammatory processes affecting the surrounding soft tissue.
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.
