Hoover lands on my left foot!

There was an incident that created merry hell back in September 2010, where a bike landed on my left foot and caused disproporationate pain and chaos. This evening, my little hoover fell on to the same spot on my lateral left ankle/foot, where there has been both a previous trauma and a sprain. There is widespread pain and tingling and pins and needles in both my hip and ankle. I just seriously hope I can appease it somehow because I am going on holiday for 2 weeks and there is no K to rescue me!
