Sounds like gout to me. I had the very same thing in my right foot. My family on my Dad's side has a history of gout and I beleive it was brought on by a visit to Boston in which I drank beer and ate lobster, shrimp and red meat. I now control intake of all alcohol, shell fish and red meat. Every person with gout is affected differently. As you know, the pain is extreme and you don't want to get it again....but you likely will...be prepared with pain killers and anti-inflamatory medicine. Good Luck
