Common causes of swollen fingers include finger soft tissue injury caused by trauma, hyperuricemia, osteoarthritis, etc. When the finger is injured by trauma, if it affects the local soft tissue, there will be pain and swelling in the finger. If you frequently consume seafood, animal organs, and other foods high in purine content, it may lead to abnormal purine metabolism in the body, causing uric acid to accumulate in the finger joints, which can also cause finger pain and swelling. The swelling of the fingers is generally caused by the following reasons:

1. Finger Soft Tissue Injury

It is more common in patients with local soft tissue injury caused by trauma, resulting in pain and swelling. External application of blood-activating and pain-relieving ointments, such as Jinhuangsan ointment, and oral medication such as Zhongtong'an can promote the absorption of local inflammation and reduce the symptoms of finger pain and swelling.

2. Hyperuricemia

Long-term consumption of animal organs, seafood, and other purine-rich foods can lead to abnormal purine metabolism in the body, resulting in the accumulation of a large amount of uric acid in the finger joints, causing pain and discomfort. Methods such as external application of Xuanming powder, oral colchicine, and reducing the intake of purine-containing foods can reduce the symptoms of finger pain and swelling.

3. Osteoarthritis

This degenerative inflammation of the joints can also cause finger swelling. A simple way to diagnose this condition is that you can no longer wear your original ring on the finger joint. This age-related arthritis is caused by the wear and tear of the cushioning tissue at the end of the joint. Osteoarthritis is often accompanied by pain and stiffness. If the pain and swelling are severe, it is necessary to seek medical attention promptly.
