I talk with people who did it and they all wait 8-9 month to walk without crutches. I can’t believe you can walk without support after 4-5 month because you’re consolidation is not done yet so how it could be possible..
you can ask to the veteran of this forum or the dr you will see
I will do my shin in November so if it was 4/5 month I will be happy ahah but we have to be realistic it’s impossible !
