I had minor Achilles tendinitis. I didn't ride (I mean, I sat on my horse and walked around for 5 minutes once but...) for a couple of weeks, maybe two or three, but I don't remember the exact amount of days really. I know it might be tough, but there are things you can do to get past it. It honestly ended up being a blessing in disguise for me. You know, sometimes I get frustrated the way things work out, but my injury was actually a positive experience for me. There is some positive part of your injury, as horrible as it may seem, and you may realize it and you may not. Just push on and realize you are tough. If you miss this show, I know it's a downer, but you'll get past it and experience other amazing shows in the future I assume. So as my friend kept telling me, get focused on getting better and don't push yourself until you know you are ready. I'm sorry that you are hurt, and I hope that you feel better soon. (:
