Painful swelling in the finger joints can be caused by other clinical conditions if symptoms caused by rheumatoid rheumatism are excluded. First, we should consider whether there is a history of trauma, such as contusions and crush injuries that may cause ligament and tendon injuries, resulting in painful swelling of the finger joints. Second, clinically common diseases such as osteoarthritis, carpal tunnel syndrome, tenosynovitis, and cervical spondylosis can also induce painful swelling of the finger joints: 1. Osteoarthritis: Osteoarthritis occurs in middle-aged and older women, and is a relatively common joint disease that is dominated by damage to joint cartilage and involves the entire joint tissue. Age, gender, obesity, genetics, trauma, strain, infection and other risk factors for the development of osteoarthritis. The main manifestations are pain, stiffness, swelling and limited movement of the finger joints at the site of the lesion; 2, carpal tunnel syndrome: also commonly known as mouse hand, is a nerve entrapment syndrome caused by the compression of the median nerve, the disease is most likely to long-term use of the wrist occupational groups, frequent and repeated use of the hand and wrist also induced the disease. Patients often feel numbness and pain in the wrist, middle finger, index finger and thumb, which can be accompanied by joint swelling, and the symptoms can generally be relieved after rest; 3, tenosynovitis: patients with tenosynovitis can experience painful swelling of the fingers, limited joint movement, and generally have morning stiffness, which can be relieved after activity. It is usually caused by chronic strain, and can be relieved by rest and local massage; 4, cervical spondylosis: patients with cervical spondylosis can be accompanied by vasomotor nerve symptoms, which can lead to numbness and pain in the upper limbs, swelling and pain in the finger joints. In addition, tendon sheath cysts, gout, fasciitis, bone spurs and other disease factors can cause the above symptoms, as well as if there is neuralgia may also be mistaken for finger joint pain and swelling. If you want to clarify the cause of the disease, it is recommended to seek medical attention promptly, and CT or MRI tests can be used to help diagnose.
