still broken foot!!!!

hallo I have broken my foot anoher time in the same bones that were broken 4 mounths ago. the fact is that the old fractures weren’t healt. i’m in cast for 6 weeks and then i’ll be in hard bandage 3 or more weeks. why does it need so much time and pain? i’m 19 and in good shape and before I had 1 splinted bandage and 2 casts, 4 mounth immobilization and 3 of crutches. is too much for a foot isn’t
