Red, swollen and painful joints in the foot are the main manifestations of gout attacks in the foot, especially in the first metatarsophalangeal joint. Gout is a crystal-related arthropathy caused by urate deposition. If urate crystals are deposited in the foot joints, it can lead to joint inflammation, which can be divided into acute arthritis and chronic arthritis according to the duration of onset and severity of symptoms. The acute arthritis phase is characterized by sudden onset of unilateral foot joint redness, swelling and pain, especially in the first metatarsophalangeal joint, which is most frequent at night or during sleep in the early morning. In acute arthritis, the joint swelling and pain are mostly self-limiting, even without the use of drugs, the joint symptoms can be relieved within a few days or 2 weeks, or even disappear. However, if the disease is not well controlled, acute arthritis may occur frequently and enlarged gout stones may gradually appear, which are distributed all over the foot and gradually erode the bone surface of the joint, causing chronic joint inflammation, suggesting that the disease has entered the chronic arthritis stage. At this time, the degree of joint swelling and pain is lighter than that of acute arthritis, but it lasts for a long time and can even lead to joint deformity and affect joint function. Gout stones in the foot may also break down and bleed white urate crystals, which may not heal for a long time and even induce infection. Therefore, redness, swelling and pain in the joints of the foot is the main manifestation of gout attacks in the foot, and there are differences between the acute arthritis stage and the chronic arthritis stage according to the length of onset and the severity of symptoms.
