One of my GP friends who may know a bit more thinks it's extensor tendinitis in the big toe from over exertion. It exhibits the same symptoms as gout but either way it's horrendous!
It's really swollen on the right foot but it's not red - tenosynovitis. Anti-inflammatories, calf stretching and ice seem to be the order of the day. Could last a week, if it's still painful after 7 days then I'll have to see a GP.... Really bad timing!
