On April 27th of this year I fell off of my horse and she stepped on my ankle. I broke every bone in my ankle, shattered my fibula, and tore every tendon and ligament. Needless to say, things looked bleak. I had a bone graft, a plate over 6 inches long, and 11 screws put in.
Sunday I got back on my horse and it was AWESOME!
My advice to you is wait. You have years to ride again, but if you keep hurting it your likely to be in pain for so much longer and maybe ruin the chance you had to ride.
I was off for almost 6 months and it was torture, but worth it because now I can ride and know I'm not going to hurt myself because I'm starting too early.
Good luck!!!!! I know how hard it is.
