Introduction
Finger joint pain may be caused by non-pathological factors such as exposure to cold, or by pathological conditions such as tenosynovitis and rheumatoid arthritis. If local warmth is not maintained, cold exposure can lead to capillary constriction, reduced peripheral blood circulation, and subsequently cause muscle contraction, spasms, and soreness. It is important to keep the area warm; wearing gloves when going outdoors is recommended.

Generally, finger joint pain may be caused by non-pathological factors such as exposure to cold, or by pathological conditions such as tenosynovitis or rheumatoid arthritis. A detailed analysis is as follows:

I. Non-pathological factors

If local warmth is not properly maintained, localized cold exposure can cause capillary constriction, reducing peripheral blood circulation and leading to muscle contraction, spasms, and soreness. It is important to maintain adequate warmth; wearing gloves when going outdoors and performing local massage may help accelerate blood circulation and relieve symptoms.

II. Pathological factors

1. Tenosynovitis
Inflammation results from excessive friction of the tendon sheath, causing fluid accumulation in the joint area, which compresses surrounding tissues and leads to swelling and pain. Pain-relieving medications such as diclofenac sodium sustained-release tablets or ibuprofen sustained-release capsules may be used under medical guidance.

2. Rheumatoid arthritis
Abnormal proliferation of synovial tissue gradually erodes internal joint structures. As joints become damaged, symptoms such as swelling, pain, redness, and inflammation occur. Treatment may include medications such as meloxicam tablets or celecoxib capsules, used under medical supervision.

In addition to the above causes, finger joint pain may also result from cervical spondylosis, gout, bone tumors, or other conditions. Given the wide range of possible underlying causes, a comprehensive evaluation—including medical history, physical examination, imaging studies, and laboratory tests—is necessary to determine the exact diagnosis and formulate an appropriate treatment plan.
