Stiff Finger Joints: Causes and Solutions

The finger joints feel stiff?

Since I was about 15 years old, for nearly 3 years now, the joint connecting my little fingers to my palms has been stiff, making it difficult to straighten or bend them without exerting extra effort.
I also cannot hold them at a midpoint angle.
This should not be due to frequent smartphone use, as I didn't have a phone during middle school.
Over the past three years, there hasn't been any noticeable improvement or deterioration.
The joint has never been swollen or painful.
I would like to know what could cause such symmetrical stiffness in my fingers.
Additionally, my thumb was hit by a volleyball, and after a few days of pain near the palm joint, it seemed to heal, but now that joint feels loose, and occasionally, the joint in my thumb makes a cracking sound (which it didn't before).
What could be the cause of this?

Hello, some people's tendon growth does not keep up with the speed of bone growth, which can lead to tightness and stiffness in the joints.
The best way to address this issue is to undergo rehabilitation and stretching while you are still young.
The thumb issue, commonly referred to as "eating radish," is actually a cartilage injury.
For young people, rehabilitation, stretching, and heat therapy can help improve the condition, but cartilage damage will not fully recover to 100%.
Wishing you a speedy recovery.

Understanding stiff finger joints, particularly in the context of your experience, involves recognizing the potential causes and implications of your symptoms. Based on your description, it seems that you have been experiencing stiffness in the joints connecting your little fingers to your palms for nearly three years. This stiffness, characterized by difficulty in bending and straightening the fingers, could be attributed to several factors.

One possible explanation for your symptoms is a condition known as "trigger finger" or stenosing tenosynovitis. This occurs when the tendons that control finger movement become irritated or inflamed, leading to a narrowing of the sheath that surrounds the tendon. While trigger finger typically presents with pain and a catching sensation, it can also manifest as stiffness, particularly if the condition is mild or has developed gradually over time. The fact that your symptoms are symmetrical may suggest a systemic issue or repetitive strain, rather than localized trauma.

Another consideration is the possibility of joint hypermobility or laxity, especially since you mentioned that your thumb joint feels "loose" after being struck by a volleyball. Joint hypermobility can lead to increased flexibility but may also result in instability and discomfort in the joints. This could explain the popping or cracking sounds you hear when moving your thumb, which is often due to the movement of tendons or ligaments over the bones.

Additionally, while you noted that your fingers have not been swollen or painful, it is essential to consider the role of repetitive strain injuries. Even if you did not use a smartphone frequently during your middle school years, activities such as playing sports, writing, or other manual tasks can contribute to overuse injuries. These injuries can lead to inflammation and stiffness in the joints, particularly if the same motions are repeated frequently.

In terms of solutions, it is crucial to address the underlying cause of your symptoms. Here are some recommendations:
1. Consult a Specialist: Given the duration and nature of your symptoms, it would be beneficial to consult with a hand specialist or an orthopedic doctor who focuses on upper extremity conditions. They can perform a thorough examination, possibly including imaging studies like an ultrasound or MRI, to assess the tendons and joints more accurately.

2. Physical Therapy: Engaging in physical therapy can help improve flexibility and strength in your fingers. A physical therapist can provide you with specific exercises designed to enhance joint mobility and reduce stiffness.

3. Activity Modification: If certain activities exacerbate your symptoms, consider modifying your approach. For example, if you play sports or engage in repetitive hand movements, take regular breaks and incorporate stretching exercises to alleviate strain on your fingers.

4. Splinting: In some cases, using a splint to immobilize the affected finger joints can help reduce strain and allow for healing. This is particularly useful if you experience symptoms during specific activities.

5. Pain Management: If you experience discomfort, over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation. However, consult with a healthcare provider before starting any medication.

6. Monitoring Symptoms: Keep track of any changes in your symptoms, including the onset of pain, swelling, or changes in joint function. This information will be valuable for your healthcare provider in determining the best course of action.

In conclusion, while your symptoms may not currently be causing significant discomfort, addressing them proactively is essential to prevent potential complications in the future. Early intervention can lead to better outcomes and improved hand function.
