Rheumatoid arthritis pain is characterized by persistent chronic pain, and the painful joints are often small symmetrical joints, with swelling and pain in the wrist, metacarpophalangeal and proximal interphalangeal joints of the hand, and also accompanied by morning stiffness, which means that the patient cannot make a fist with both hands after waking up in the morning. In order to further clarify the diagnosis of rheumatoid arthritis, it is necessary to further check the blood sedimentation, C-reactive protein, rheumatoid factor, anti-CCP antibodies and other indicators, as well as to add methotrexate, leflunomide and other drugs for treatment as soon as possible.
