Gouty arthritis is a joint lesion caused by gout, which is a crystal-related joint inflammation mainly caused by uric acid deposition, and has different symptoms depending on the stage of the disease, including acute arthritis and chronic arthritis. The acute arthritis stage of gout is characterized by sudden onset of single joint redness, swelling and pain, mostly at night or in the morning during sleep, mostly in the foot joints of the lower limbs, most often in the first metatarsophalangeal joint, but also in the knees, fingers, wrists, elbows and other joints. At this time, patients often feel that the joint swelling and pain is severe, as if it is cut like a knife, insect bite, etc.. However, most of them are self-limiting, even without the use of drugs, the joint symptoms can be relieved within a few days or 2 weeks, or even disappear on their own. However, if the condition is not well controlled, acute gout may occur frequently and enlarged gout stones may gradually appear in the auricles, feet, hands, elbows and other places, affecting the appearance. Gouty stones in the periphery of the joints can erode the bone surface of the joints and cause chronic joint inflammation, i.e., enter the chronic arthritis stage of gout, when persistent joint swelling, pain, and even joint deformity occur. Depending on the stage of the disease, gouty arthritis also differs from the acute arthritis stage to the chronic arthritis stage.
