A 40-year-old man presents with acute severe pain and swelling in his right great toe, which started overnight. He reports it is exquisitely tender to touch.

On examination, the metatarsophalangeal joint of the right great toe is erythematous, warm, swollen, and extremely tender. What is the most likely diagnosis?
