Hi, My Name Is Leanne And I Am 25 Years

Hi, My name is Leanne and I am 25 years old. I fractured my foot a couple of weeks ago and i have a cast on at the moment. I feel that it has healed quite a bit and it doesn't hurt anymore. Its been almost 3 weeks that i have the cast and i don't have an appointment with the doctor for the next 1 month. Is it possible for me to get my cast removed at an earlier stage.
