What's wrong with finger joint pain?

　　Finger joint pain may seem like a minor problem, but it may seriously affect writing, holding chopsticks, or even dressing. Many people think that they are tired from working and just rest. However, long-term or repeated pain may be a sign of disease. With the increase in mobile phone use and aging, more and more people are experiencing finger joint discomfort. What's going on? Is it a strain injury or a sign of serious illness? Don’t ignore it, the truth may be more complicated than you think.

What's wrong with finger joint pain?

　　1. Trauma or strain

　　Being hit by a ball while playing, spraining your fingers, long-term typing or doing manual and other repetitive movements may lead to soft tissue injuries, ligament strains and even minor fractures. This type of pain usually has a clear trigger and manifests as local swelling, obvious tenderness, and limited movement.

　　2. Tenosynovitis

　　People who use mobile phones, computers or hold children for a long time are prone to tenosynovitis. Typical symptoms include soreness and pain in the finger joints or wrists, stiffness in the morning, and may "get stuck" or make a snapping sound when bending, which is medically called "snapping fingers."

　　3. Osteoarthritis

　　It is more common in middle-aged and elderly people and is caused by the degeneration and wear of articular cartilage. The finger joints will gradually deform and "bone spurs" will appear, commonly known as "old cold legs" extending to the hands. It is characterized by aggravation after activity and relief by rest, and is more obvious when the weather gets cold.

　　4. Rheumatoid arthritis

　　This is an autoimmune disease that often presents with symmetrical pain in the fingers on both sides, especially the metacarpophalangeal joints and the proximal interphalangeal joints. Morning stiffness for more than 30 minutes is an important sign. It may also be accompanied by symptoms such as fatigue and low-grade fever, and requires timely medical attention.

　　5. Gout or high uric acid

　　Although gout is more common in the toes, urate crystals may also deposit in the finger joints, causing redness, swelling, heat, and severe pain. If you have a history of drinking and like to eat seafood and offal, you should be alert to hyperuricemia.

When should you see a doctor for finger joint pain?

　　1. Pain that lasts for more than 1 week without relief

　　If finger joint pain lasts for more than 1 week and does not relieve after rest, or even affects daily grasping and bending movements, it may be a sign of arthritis, tenosynovitis and other diseases. Timely medical attention is required to avoid worsening of the condition and damage to joint function.

　　2. Accompanied by redness, swelling and heat in the joints

　　The finger joints are not only painful, but also obviously red, swollen, and hot. When touched, the temperature is higher than the surrounding skin. This may be caused by acute inflammation or infection. If not treated in time, it may cause the inflammation to spread and increase the difficulty of treatment.

　　3. Joint deformation or limited movement

　　If you find that there are deformities in the finger joints, such as thickening of the fingers, abnormal bending, or obvious limitations in movement, such as the inability to straighten or bend normally, it may be caused by diseases such as rheumatoid arthritis. It is necessary to seek medical treatment as soon as possible to determine the cause and prevent the joint deformity from getting worse.

　　4. Symptoms of general discomfort occur

　　Joint pain is accompanied by systemic symptoms such as fever, fatigue, and weight loss. It may be that systemic diseases involve the joints, such as gout, autoimmune diseases, etc. Timely medical examination can help clarify the overall condition and avoid delay in treatment.

Tips for protecting finger joints

　　1. Avoid repeated actions for a long time

　　Reduce repetitive movements such as typing, knitting, and playing with mobile phones for long periods of time every day. Stop moving your fingers every 30 minutes, make fists, and stretch to relax your joints and muscles to prevent tenosynovitis or joint pain caused by overstrain.

　　2. Pay attention to keep your joints warm and prevent colds

　　Wear gloves when going out in cold weather to avoid exposing your fingers to low temperatures； Use warm water when washing dishes and laundry, and avoid direct contact with cold water to prevent cold stimulation from worsening blood circulation in joints and inducing or aggravating joint discomfort.

　　3. Reasonable use of auxiliary tools

　　When carrying heavy objects, use your palms to lift them and avoid using your fingers only.； Wear non-slip gloves when doing housework to reduce friction and pressure on fingers ； Use a wrist rest when using the keyboard or mouse to maintain a comfortable hand posture and reduce the burden on the joints.

　　4. Do moderate joint exercises

　　Doing finger stretching exercises every day, such as straightening and bending your fingers one by one, or pinching soft balls with your fingers, for 10-15 minutes each time, can enhance joint flexibility and surrounding muscle strength, promote blood circulation, and reduce the risk of joint pain.

　　Finger joint pain is not something you can just “just put up with”. Only by distinguishing whether it is a strain injury or a disease can we treat it symptomatically and avoid delaying treatment. Early detection and early treatment can preserve the flexibility of your hands.
