Morning stiffness is the first symptom of rheumatoid arthritis. Patients may find that their joints are inflexible in the morning, but when they get up and move around, morning stiffness may decrease or disappear. Patients may also experience joint swelling and pain, as well as weakness, fatigue, fever, and other symptoms. The main symptoms and signs of the diseased joint are graded as follows: Grade 0: No pain, no pressure, no swelling, no morning stiffness. Grade 1: No pain with inactivity, mild pain with activity; pain with compression; swelling of the joint, but not beyond the bone prominence near the joint; morning stiffness within 1 hour. Grade 2: pain during inactivity, pain worsens during activity; compression not only complains of pain, but also has the expression of awe or retraction of the joint; swelling is clearly level with the bone prominence, soft tissue depression disappears; morning stiffness time is within 1~2 hours. Grade 3: Pain was severe and joint movement was significantly restricted due to pain; the patient refused to be examined by the physician for pressure pain; the joint was highly swollen and higher than the nearby bone prominence; the duration of morning stiffness was more than 2 h.
