How many horses are there to look after?
I had several surgeries and horses at home, far away from anyone, but in those days no more than three-four horses.
I think if you may have a similar situation, could you board your horses temporarily, until you are back on your feet enough to care for them?
The surgery itself seems forward enough and you should be able to do more soon, but with surgeries, you never know, so best provide for care as long as may be needed, just in case it takes you longer than what someone else could be of help.
My first surgery, I thought my neighbors could come feed for a couple days.
As it happened, I had to stay in town longer, my heart quit four times during recovery and they would not let me go home until that was stable.
After that, for any other surgery, I sent horses to board with a friend, one needs medication for Cushing’s and that took care of that worry.
As for that specific surgery, I hope someone else can tell you more.
