Pain Behind the Index Finger Joint: When to Seek Medical Help

The tendon behind the first joint of the index finger on the back of the hand is painful, likely due to an injury from exercise?

On the back of the hand, extending more than one centimeter from the first joint of the index finger, it may be referred to as the extensor tendon.
Previously, due to ball sports, the finger was jammed, and it hurts whenever the finger is straightened.
However, after using adhesive tape and ointment for a week, there has been no improvement.
I'm unsure which specialist to consult, as the pain may be related to either tendon issues or bone problems, given the overlapping pain points.

Dear Mr.
A,
Please make sure to visit an orthopedic or hand surgery outpatient clinic soon.
It could be due to ligament injury, nerve damage, inflammation of the distal interphalangeal joint, or other causes!

More Info

When experiencing pain behind the index finger joint, particularly after an injury such as a jammed finger from sports, it is important to assess the situation carefully to determine whether medical intervention is necessary. The pain you describe, located at the dorsal aspect of the first joint of the index finger, could be associated with several conditions, including tendonitis, ligament injuries, or even a fracture, depending on the severity of the initial injury and the symptoms you are experiencing.

Given that you have already applied topical treatments and have not seen improvement after a week, it is advisable to seek medical attention. The fact that the pain persists and is aggravated by certain movements, such as extending the finger, suggests that there may be an underlying issue that requires further evaluation.
In terms of which medical specialty to consult, starting with an orthopedic specialist would be appropriate, as they specialize in musculoskeletal injuries and conditions. They can perform a thorough examination, which may include physical assessments and imaging studies like X-rays or MRI to rule out fractures or other structural issues. If the problem is determined to be related to the tendons or ligaments, a referral to a hand specialist or a physical therapist may be recommended for rehabilitation.

It is also important to consider the possibility of conditions such as De Quervain's tenosynovitis, which is characterized by pain along the thumb side of the wrist and can radiate to the index finger. This condition is often exacerbated by repetitive motions and may require specific treatment strategies, including splinting, anti-inflammatory medications, and physical therapy.

In summary, if you are experiencing persistent pain behind the index finger joint that has not improved with conservative measures, it is prudent to seek medical evaluation. Early intervention can help prevent further complications and facilitate a more effective recovery. Remember, pain that does not improve over time or worsens with activity is a signal that further investigation is warranted.
