Swollen fingers can be painful and alarming, particularly if you haven't experienced any trauma to the area and don't know what is causing your condition. Swollen fingers without trauma can be caused by different diseases, conditions or infections.
The most common form of arthritis that can lead to swollen fingers is rheumatoid arthritis, as reported by the National Institutes of Health. The swelling and pain may come and go.
According to the National Institutes of Health, gout is more commonly associated with the feet and ankles, but it can affect hands and fingers as well. It occurs when uric acid builds up in the body and crystals form in the joints, causing pain, redness and swelling.
Lupus is an autoimmune disease that, like rheumatoid arthritis, can cause the fingers and hands to swell. The National Institutes of Health reports that lupus is nine times more likely to affect women than men.
If you've recently had a small cut or abrasion on your finger, it is possible that an infection has caused your swollen finger. According to the National Institutes of Health, redness, pain and an area that is "hot to the touch" can be other signs of an infection on your finger.
Treatment will vary depending upon the cause of swollen fingers, so it is important to visit a medical facility to determine the exact cause. Some treatments may be as simple as applying a cream or lotion, while others may involve numerous medications and possibly surgical procedures.
