What causes black finger joints?

Many people have encountered the phenomenon of black finger joints, especially among middle-aged and elderly people. This may be related to their long-term lifestyle and work habits. The change in color of finger joints is not a normal phenomenon and requires careful observation to find the cause. Let’s take a look at the causes of black finger joints.

1. The dark color of finger joints indicates a lack of B, which makes it difficult to produce blood and causes insufficient oxygen, resulting in dirty blood and dark skin. Vitamin B complex exists in grains and beans and is an important substance for maintaining human health. If you drink a lot of water or exercise a lot, the body's B vitamins will be consumed and water metabolism disorders will occur.

2. It may be due to one’s physical constitution, which is physiological. It may also be amyopathic dermatomyositis, which is a connective tissue disease. Common symptoms are rashes on the extensor side of joints, such as dark red rashes on the extensor side of hand joints and elbows. It is recommended that you go to the relevant department of the hospital for treatment, check ANA, ENA, and muscle enzyme spectrum, and do a skin biopsy if necessary, to find out the cause.

3. Rheumatoid arthritis

Rheumatoid arthritis is a physical disease characterized by non-suppurative inflammation of the joints and peri-articular tissues, often accompanied by extra-articular symptoms, hence the name rheumatoid disease. Inflammation, exudation, cell proliferation, granuloma formation of the synovium in the joint cavity, destruction of cartilage and bone tissue, and finally ankylosis and dysfunction of the joint. It often invades small joints, such as hands, feet and wrists. It is often symmetrical and has a chronic course with temporary relief. Due to multi-system damage, autoantibodies can be detected in the serum, so the disease is considered to be an autologous disease. The age of onset is mostly between 20 and 40 years old. There are more women than men.
