Swelling and Pain in Finger Joints: Possible Causes - Orthopedics

More Info

---

Hello! Thank you for your question regarding the swelling and pain in your finger joints, particularly in the metacarpophalangeal (MCP) joints of your left hand. Based on your description, there are several potential causes for the symptoms you are experiencing.

Firstly, the swelling and pain in the MCP joints could be indicative of a few conditions, including but not limited to arthritis, tendinitis, or even a possible injury that may not have been fully recognized at the time it occurred. Given that the swelling has persisted for over a week and has become hard, it is essential to consider the following possibilities:
1. Arthritis: This is one of the most common causes of joint swelling and pain. There are various types of arthritis, including osteoarthritis and rheumatoid arthritis. Osteoarthritis typically occurs due to wear and tear on the joints, while rheumatoid arthritis is an autoimmune condition that can cause inflammation in the joints. In your case, if the swelling is symmetrical and involves multiple joints, rheumatoid arthritis could be a consideration. A blood test can help determine if there are markers for rheumatoid arthritis.

2. Tendinitis: This condition occurs when the tendons around the joints become inflamed. Activities that involve repetitive motion, such as typing, knitting, or other manual tasks, can lead to tendinitis. If you have been engaging in such activities, this could be a contributing factor.

3. Injury or Trauma: Sometimes, a minor injury can lead to swelling and pain that may not have been immediately apparent. If you have recently engaged in activities that put stress on your fingers, such as lifting heavy objects or performing repetitive tasks, this could lead to localized swelling and discomfort.

4. Ganglion Cyst: These are fluid-filled sacs that can develop near joints or tendons, often causing swelling and discomfort. They can sometimes feel hard to the touch and may fluctuate in size.

5. Infection: Although less common, an infection in the joint or surrounding tissue can cause swelling, pain, and sometimes redness or warmth. If you notice any signs of infection, such as fever or increased redness, it is crucial to seek medical attention promptly.

Given that the swelling has not decreased and the area has become hard, it is advisable to seek a thorough evaluation from a healthcare professional, preferably an orthopedic specialist. They may perform a physical examination, imaging studies (such as X-rays or MRI), and possibly laboratory tests to determine the exact cause of your symptoms.

In the meantime, you can consider some conservative management strategies to alleviate discomfort. Resting the affected fingers, applying ice to reduce swelling, and taking over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain and inflammation. However, these measures should not replace professional medical advice.

In summary, while there are several potential causes for the swelling and pain in your finger joints, a thorough evaluation by a healthcare professional is essential for an accurate diagnosis and appropriate treatment plan. Please take care, and I hope you find relief soon!
