What causes pain in the middle finger joint of the hand?

Generally, pain in the middle finger joint may be caused by overuse, exposure to cold, tenosynovitis, rheumatoid arthritis, gout, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Overuse: Prolonged repetitive fine movements of the middle finger, such as typing or playing musical instruments, may lead to muscle fatigue and cause pain. Excessive use of the fingers should be avoided, and appropriate rest and gentle movement are recommended.

2. Exposure to cold: Remaining in cold environments for extended periods or failing to keep the fingers warm may impair local blood circulation, resulting in pain in the middle finger joint. Keeping the fingers warm is important; local heat application, as directed by a physician, may help relieve discomfort.

3. Tenosynovitis: Repeated friction of the flexor tendons within the tendon sheath can cause aseptic inflammation of the sheath tissue, leading to pain, restricted movement, and tenderness in the middle finger joint. Patients may take medications such as celecoxib capsules, ibuprofen sustained-release capsules, or dexamethasone acetate tablets as prescribed by a doctor.

4. Rheumatoid arthritis: This is a chronic systemic autoimmune disease that can affect the synovial tissue of the middle finger joints, causing joint swelling, deformity, and pain. Patients should follow medical advice for treatment; commonly used medications include Qingpeng ointment, hydroxychloroquine sulfate tablets, and azathioprine tablets.

5. Gout: Hyperuricemia leads to deposition of urate crystals in the joints, triggering acute arthritis with inflammatory responses such as redness, swelling, heat, and pain, which may occur in the middle finger. Patients may take medications such as benzbromarone tablets, colchicine tablets, or allopurinol tablets as directed by a physician.

During recovery, adequate rest is essential. Heavy physical labor should be avoided to prevent worsening symptoms and potential harm to finger health.
