Sudden swelling and pain in a single finger can be caused by various factors, commonly including the following:
1. Trauma: Swelling and pain can result from impacts, sprains, or pressure applied to the finger.
2. Arthritis: Conditions such as rheumatoid arthritis or osteoarthritis may also lead to finger swelling and pain, particularly noticeable in the morning or after prolonged hand use.
3. Infection: Bacterial or fungal infections can cause redness, swelling, warmth, pain in the finger, and even formation of pus.
4. Tendinitis: Overuse of the fingers, such as typing or playing a musical instrument for extended periods, may result in tendinitis, presenting as pain and swelling at the base of the finger.
5. Gout: Gout caused by hyperuricemia can also affect the fingers, often suddenly occurring at night with severe pain.
6. Non-infectious factors: Allergies and contact dermatitis, as well as rheumatic diseases such as rheumatoid arthritis, may also cause sudden swelling and pain in the fingers.
If finger swelling and pain persist or are accompanied by symptoms such as fever or erythema, it is recommended to seek immediate medical attention at a hospital.
