The symptoms of finger joint swelling and pain in the morning may be due to rheumatoid arthritis. Rheumatoid arthritis is a very common clinical bone and joint disease. In patients with rheumatoid arthritis, there is a large number of inflammatory cells infiltrating the synovial membrane of the joints, resulting in the destruction of cartilage and bone tissue, which causes joint swelling and pain. The most common symptom of rheumatoid arthritis is morning stiffness, which occurs when the patient wakes up with joint immobility and swelling pain. In addition, some patients with severe rheumatoid arthritis may have deformed joints and may have multiple organ involvement, including the heart, lungs, and kidneys.
