Gout pain is usually most commonly felt in the first metatarsophalangeal joint, and can occasionally occur in other joints. The majority of gouty arthritis attacks only a single joint at the onset, with the first metatarsophalangeal joint being the most common, and the pain is usually asymmetric, occasionally occurring in other joints as well. Depending on the frequency of attacks, the other joints most commonly affected are: foot, ankle, heel, knee, wrist and elbow. Acute gout often occurs suddenly at night, with progressive increase in pain, redness, swelling, heat, pain and functional limitation of the joints at the onset of the attack, and some patients may have low-grade fever, chills, headache, palpitations and nausea and other systemic symptoms. Chronic gout stone lesion stage manifested as subcutaneous gout stone and chronic gout stone arthritis. Subcutaneous gouty stone occurs typically in the auricular region, and is also commonly found around recurrent joints and in areas such as the Achilles tendon and patellar bursa. Gouty stones often coexist with chronic gouty stone arthritis. Symptoms are persistent joint swelling and pain, tenderness, deformity and dysfunction. Middle-aged and elderly men who experience recurrent episodes of severe pain in a single metatarsophalangeal toe and other joints should go to the hospital in a timely manner. Doctors determine the patient’s diagnosis based on the typical symptoms of a gouty attack combined with the results of an examination. Patients diagnosed with gout need to be treated professionally under the guidance of a doctor, and at the same time live on a low purine diet as much as possible.
