Common causes of swollen fingers are injuries, infections, and degenerative or autoimmune disorders, according to HealthGrades. Inflammatory conditions, such as bursitis and rheumatoid arthritis, are also associated with finger swelling.Continue Reading
Injuries that cause swollen fingers include broken bones, lacerations, blunt force trauma, damage to ligaments or cartilage, and injuries caused by repetitive stress on the fingers. Cellulitis, carpal tunnel syndrome, osteoarthritis, aronychia, which is an infection around the nail, and septic arthritis are additional causes, notes HealthGrades.
Complications associated with swollen fingers that go untreated include chronic disability, deformities, the inability to do daily tasks and the spread of an infection to other areas. If a swollen finger goes untreated, it may require amputation or surgery to repair damage, states HealthGrades. If the swelling persists or causes pain or other symptoms, HealthGrades recommends seeking medical attention as soon as possible. A swollen finger also requires medical attention if is accompanied by a fever above 101 degrees Fahrenheit or is visibly deformed.
Bruising or discoloration, chills, fatigue, stiffness, or painful and tender areas may also occur. Lumps or bumps on the finger, numbness or a tingling sensation, reduced range of motion, and lacerations or cracks filled with pus are other symptoms, adds HealthGrades.Learn more about Pain & Symptoms
