i broke mine about two months ago, and i was recently put Back in a cast because i was rushing the healing. i asked my doctor how to speed up healing so i wouldnt need surgery and he told me to STAY OFF OF IT as much as possible... to be totally immobile. which sounds impossible, but worth it. you dont want your bone to get Worse while in that cast (it Can happen- i achieved this somehow) so as long as you dont walk on it too soon, youll be fine.
as for retraining yourself to walk properly, im no expert so i could be wrong... but (because i Had a boot for a few weeks) i just used my crutches for a few days in case my foot flaked out on me, and started walking..
at First it hurt- like a shocking feeling, but then i got some strength and was fine.... although i think my foot will have to be retrained to Bend again! cuz it was real stiff
haha but what do i know? i was just recasted for being an idiot about this bone!!
okay, so i have pretty bad advice.. but the first part was True. you really do have to keep off of it until you get the okay from the doctor dude
