I've been there, done that.
I was also kicked while mounted resulting in a broken leg. I had to ride a mile to get back to the barn, where I passed out in the parking lot. Luckily I was training horses for an orthopedic surgeon who whisked me to his office for treatment. When he tried to cut off my custom boot, I made him pull it off. He told me my leg couldn't be broken or I would have been screaming when he pulled it off.
When he came back with the x-ray, he took that comment back. I laughed and told him I WOULD have screamed if he had taken scissors to my beloved boots.
I couldn't be cast for several days, but once I was I was determined to ride. I led the horse to a mounting block in crutches. Got on bareback, as my leg couldn't get in stirrups, and just hacked. The doctor didn't clear me....he knew better than to try to stop me.
However, you need to talk with your doctor. When you are able to get in a walking cast (weight bearing) I see no reason you can't get on a RELIABLE horse for hacking. I took more risks than I would ever suggest you make.
I rode in an event with my leg in a splint. I was riding the doctors horse and he put me in a removable cast with a splint back-up. I was not able to flex my ankle so had to ride with a longer stirrup. definitely a unique experience I hope never to repeat.
While I almost never bought show photos, I did buy this one from that show
Be careful, but you may find you can ride sooner than you think.
