I have a pair of shoes that cuts too tight across the top of my left foot after walking in them all day. A few months ago, I realized the top of my left big toe and the second toe were totally numb. I went to my GP and he was totally unconcerned - said I impinged a nerve, that it should get better and I should come back in in a couple of months. I was just about to schedule the follow-up when I realized the feeling has started to come back.
You went clubbing and your shoes impinged a nerve and made your toe numb. The feeling will come back, but it can take some time - nerves take a lot of time to grow back.
(Btw - the hearing loss after going to a club or concert is universal - it happens to everyone. In the future, I know it sounds dorky, but consider wearing earplugs. You don't want to wind up with hearing aids when you're 50.)
