It's great that you were able to get back on, even if it's just a little bit right now. I got kicked by a pony that was in training and snapped two bones in my hand, so they casted me to the elbow, and I was still riding. I was jumping 3 ft at home, with one hand, and wanted to go to a show. My darling hubby told me I could show with my cast, but only if I'd ride on the flat only, just to be safe. My horse was so grouchy that he wasn't jumping that he jumped out of the arena and took off for the trailer. I'd have been better off jumping on purpose than clinging on for dear life with something like that. Just make sure you are careful and that you know your horse and their moods well, and you'll be fine.
