Why is the middle finger joint swollen and painful? Three reasons need attention

In daily life, the joints of fingers will show obvious swelling and pain symptoms after being injured. Generally speaking, after the middle finger joints are found to be swollen and painful, the common causes are mainly related to the following three points.

1. Osteoarthritis of joints

This is also the reason for swollen and painful finger joints. The main manifestations of this condition are: swelling, and bony growths in the joints - bone spurs. It often occurs at the end joints of the fingers, but can also occur in the joints between the fingers. Hyperplastic arthritis usually occurs in older people, often over 40 years old, first appearing in one or several fingers, and then affecting other fingers. The affected joints may become red, swollen and painful. Morning stiffness is common and can be severe but lasts only briefly, less than 20 minutes. X-ray examination showed bone hyperplasia.

2. Septic arthritis caused by bacterial infection

Rheumatoid arthritis and rheumatoid arthritis caused by autoimmune or allergic reactions, gouty arthritis caused by metabolic disorders, and traumatic arthritis caused by trauma, etc.

3. Bone hyperplasia

This is the most common cause of swollen and painful finger joints, caused by tissue degeneration and cumulative strain, and is more common in obese and overweight middle-aged and elderly people. The most common sites of the disease are the knees, fingers, neck, and lumbar spine. The main symptoms are joint pain and stiffness (the pain will be relieved after slight activity). In severe cases, joint swelling and muscle atrophy may occur.
