What is the difference between gout and rheumatoid arthritis?

Gout is a joint disease caused by urate deposition, characterized by sudden and severe swelling of a single metatarsophalangeal joint or ankle joint. Colchicine is the first-line treatment for this disease, while rheumatoid arthritis is a chronic connective tissue disease caused by genetic and infectious factors, characterized by symmetrical and migratory pain in knee, ankle, wrist, etc., usually requiring treatment with salicylic acid preparations and adrenocortical hormones.
