Gout looks like a slight, reddish swelling in the affected joint. More Info: Though the symptoms of gout visible by the naked eye are minor, the pain is usually severe.
Incidentally, gout is caused by the kidneys producing too much uric acid, which collects in joints (not the kind you're thinking of), mostly joints that have been injured in activities like sports. The acid is in crystal form, and it feels like razor blades scraping away at the joint....which is, in essence, what is happening.
