Hardness of finger joints is not necessarily gout, but may also be rheumatoid arthritis and other diseases. If the stiffness of the finger joints is caused by gout, which usually occurs late at night or in the early morning, and sudden redness, swelling, heat and pain in the finger joints, it is recommended to go to the regular hospital to check the blood uric acid, to observe whether there is an increase in blood uric acid, and urate crystals can be seen in the CT imaging of the joints. There are many reasons for stiffness of finger joints. Besides gout, rheumatoid arthritis, carpal tunnel syndrome, and injuries to the joint capsule, tendons or ligaments of the hand can also cause stiffness of finger joints. If no urate crystals are seen in the above tests and there is no abnormality in the blood uric acid index, then the stiffness of the finger joints is usually caused by other reasons, such as rheumatoid arthritis, carpal tunnel syndrome, etc. It is recommended to improve the joints of the frontal and lateral X-rays, blood sedimentation, etc., to make a clear diagnosis. Patients with stiff fingers are advised to go to regular hospitals to find out the cause of the stiffness and follow the doctor’s instructions for standardized treatment.
