In the head and jaw. In the lower back.
I think I was 6 and went running behind a pony mare to see her foal. WHAM she nailed me in the head and jaw. Concussion and some stitches. I had a lump on the side of my head and face for over 2 months. ( I got grounded from the barn for over 6 months because I didn't listen to my Mom and got kicked.
The lower back ties with the face and jaw for worst injury. I was going behind my mare to pick the feet on the other side, dropped my hoof pick, bent down to get it, stood up, and that is all I remember til 2 days later in the hospital. I injured my spine in 2 places, where her hoof connected, and where I went flying head first into the side of the barn.
I don't tolerate a kicky horse anymore PERIOD.
