Dry syndrome may cause finger joint pain, but finger joint pain may also be caused by rheumatoid arthritis, osteoarthritis and other diseases. 1. Dry syndrome: dry syndrome disease can involve the joints and lead to corresponding symptoms, mostly in the hand joints, pain is chronic, recurrent, most of the time is not serious, so dry syndrome may cause patients with finger joint pain. 2. Rheumatoid arthritis: rheumatoid arthritis mainly involves the surrounding joints and leads to joint pain, morning stiffness, joint swelling and other symptoms, and when the disease involves the finger joints, it will lead to the joint pain. 3. Osteoarthritis: the condition of osteoarthritis is not yet clear, the main clinical symptom is joint pain, so patients with finger joint pain may also be caused by osteoarthritis. There may be other reasons for finger joint pain, so we suggest that patients go to the rheumatology and immunology department or orthopedics department of regular hospitals for further diagnosis.
