Cold and Painful Left Index Finger Joint: Possible Causes and Solutions

The front joint of the left index finger is painful and cold to the touch?

The front joint of my left index finger hurts and feels cold when pressed.
I haven't sustained any injuries recently.
I visited an orthopedic doctor and had an X-ray done, which showed everything to be normal.
However, the front joint of my left index finger still hurts when pressed, and the colder the weather gets, the colder my left finger feels.
Only my left index finger is cold and painful, while the other four fingers are normal.
This pain has persisted for about a month.

Dear Wen-Chieh, you mentioned that "pressing the proximal joint of the left index finger causes pain and it feels cold." One key point is that "the colder the weather, the colder the temperature of the left finger," indicating that circulation in the area above the left index finger or the affected site is compromised.
The primary reason for this compromised circulation could be an injury (whether recent or old), while other causes of circulatory issues would require further information.
Based on your description, it is suspected that an old injury may be causing the current joint pain, and the cold weather along with chronic strain could also be contributing to the worsening of the problem.
Please seek assistance from a physician nearby.

Wishing you a speedy recovery!

More Info

Mimi, thank you for sharing your concerns regarding the pain and cold sensation in your left index finger joint. Based on the symptoms you've described, there are several potential causes that could explain your condition, and I will outline them along with possible solutions.

Possible Causes
1. Rheumatoid Arthritis (RA): Although you mentioned that your X-ray results were normal, RA is a possibility, especially given that it can sometimes present with joint pain and swelling without visible changes on X-rays in the early stages. RA typically affects multiple joints symmetrically, but it can also start in a single joint. Symptoms include joint stiffness, especially in the morning, and pain that may worsen with activity.

2. Osteoarthritis (OA): This is a degenerative joint disease that can cause pain and stiffness in the joints. It is more common in older adults and can lead to joint inflammation. OA may not always show significant changes on X-rays initially, especially in its early stages.

3. Tendonitis: Repetitive use of the fingers, particularly in activities like knitting or crocheting, can lead to inflammation of the tendons around the joints, causing pain and discomfort. This condition can be exacerbated by cold weather, which can increase stiffness and pain.

4. Raynaud's Phenomenon: This condition causes some areas of your body, usually your fingers and toes, to feel numb and cold in response to cold temperatures or stress. It can cause the fingers to turn white or blue and may be associated with other conditions, including autoimmune diseases.

5. Nerve Compression: Conditions such as carpal tunnel syndrome or ulnar nerve entrapment can lead to localized pain and cold sensations in the fingers. Although you mentioned that other fingers are normal, localized nerve issues can still cause symptoms in a single digit.

Recommended Solutions
1. Rest and Activity Modification: If your symptoms are related to overuse, it’s important to rest the affected finger and modify activities that exacerbate the pain. Consider taking breaks during activities that require repetitive finger movements.

2. Heat Therapy: Applying heat to the affected area can help alleviate pain and stiffness. Warm compresses or heating pads can be beneficial, especially before engaging in activities that may cause discomfort.

3. Cold Therapy: If you experience swelling, applying ice packs can help reduce inflammation. However, since you mentioned that your finger feels cold, be cautious with ice application.

4. Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help reduce pain and inflammation. Always consult with a healthcare provider before starting any medication.

5. Physical Therapy: A physical therapist can provide exercises to strengthen the muscles around the joint and improve flexibility. They can also teach you techniques to reduce strain on your fingers during activities.

6. Consultation with a Specialist: If symptoms persist, consider consulting a rheumatologist or a neurologist. They can perform further evaluations, including blood tests for autoimmune markers or nerve conduction studies, to rule out conditions like RA or nerve compression syndromes.

7. Lifestyle Adjustments: Keeping your hands warm in cold weather is essential. Wearing gloves or using hand warmers can help maintain blood flow and reduce symptoms.

In conclusion, while the pain and cold sensation in your left index finger joint can be concerning, there are various potential causes and solutions to explore. It’s important to monitor your symptoms and consult with healthcare professionals for a comprehensive evaluation and tailored treatment plan. Wishing you a speedy recovery and relief from your symptoms!
