So I broke my foot in the area of metatarsal that's what the doctor said and he couldn't put a cast on till my swollen went down and it took like three weeks for it to go down and then he would cast it. So now I just got my cast Tuesday and he told me were I broke it looked more open and instead of heeling it opened more and I mite need screws depends if the cast will help after a month with my cast on. do you think I will need screws ?
