I feel your pain brother. Three weeks ago I was trying to finish break a 7yr old (15.3hn) freshly cut paint stud. I saddle him up and hit the pavement. Two bucks forward and one rear back and my head slams the pavement. Thats all I remember. My buddies said I was out cold for a few minutes. The only good thing about getting knocked out is that I can't remember if it hurt or not.

. My wife took me also to the hospital for a ct scan. Doc said only a concussion. "Dodged another bullet". Really sorry to hear about your injury. Thats going to be a hard one to heal and probably even harder one once you get back in the saddle. Good luck on the recovery.....
P.S. "True Story"; I actually sold my dirt bike about twelve years ago and bought my first horse because I thought that horses would be much safer. Looking back, I still wonder if I should have not sold the bike.
