So sorry to hear about your accident! I can share some advice.
A few years ago, I was launched off my spicy mare and landed feet first. I broke the end of my tibia. I opted for surgery. The surgeon placed two screws to reattach the piece that broke off. The first four days after surgery were quite painful, but I healed really fast.In about a month and I was walking in street shoes, which surprised the surgeon.
While healing, I got a knee scooter and was pretty mobile. I also got a shower bench (pic below) and that was so helpful. I used it two years later when I shattered my femur in a non-riding accident. I could slide off my wheelchair on to the bench and shower while sitting.
Good luck and quick healing. Breaking a bone is never fun. Is your healing time longer because you didnāt have the bone reattached via surgery?
