If you have anyone who is willing to ride or lunge your horse that would be very helpful. But if you are uncomfortable with the thought of someone else riding your horse you could just free lunge him or hand walk him.
I hope this helps and that you get better soon!!
my Suggestion is to ask to have your horse put into a pasture while you are unable to ride that way he/she will be able to move around daily and then on top of that I would ask if anyone would lunge or flat your horse until you can ride again! :) (I hope your foot heals soon so you can ride!!)
