The first gout attack I had was the worst. I had been limping for two weeks thinking it would just go away, but it got steadily worse until it became unbearable and I went to the doctor. The diagnosis was almost instantaneous. She looked at my foot and went "Yep, gout". It got worse for another couple of days until it slowly started ebbing away. I was basically a cripple for at least two weeks though.
I have it better under control now, but it still plays up sometimes. Gout sucks, but also there are worse things I suppose.
