I was given some good advice by my trainer when I had a particularly bad fall which was, "Get up, dust yourself off, take a deep breath and get back on. It was a long way from your heart." It might not be easy but I have found that it's crucial to get back on as soon as possible and try again.
How I personally overcome a fall is as follows: While I'm falling and/or on the ground I make sure I know exactly where the horse is and get up as quick as I can. I take a deep breath and pat my arms and legs down and see that I'm not missing any body parts or have any bits sticking out of me and then I shrug it off. That was then, this is now. Over analyzing it won't help any so the best thing to do is chug on and fix the problem. I tell myself that I must get back on the horse (or any for that matter) within thirty minuets. When I get the horse I might take it in a smaller arena or simply just walk it around or trot a little but I always make sure that me AND the horse end on a good note and in a good place mentally.
I one time fell head first while cantering my mare (through rider error and a spunky horse lol) when I was ten. It scared the crap out of me. I got back on within five minuets and walked and trotted around but didn't canter. Years later I still had a fear of cantering so my trainer made the best decision for me: whenever she put me on a horse she made me canter the entire time. If I stopped or got off she would literally chase me around with a lunge whip (me on the ground, not the horse(s) which just stood there while I ran around screeching). For three weeks I did nothing but canter, and on week four I didn't have that fear anymore. Same's true for if you have a fear after a fall. Expose yourself to it and muddle through it. If you have to, find someone who will chase you around with a horse whip if you stop or get off and push through it until it becomes comfortable again.
Now the remedies from the bruises afterwards are many. Personally I like a nice hot shower to loosen up my muscles and then I crash on the couch for a couple of hours. After that I'm up and moving, just like horses after a trauma you keep them moving so you don't tie up and are in double the pain. On rare occasions I've taken a couple of asprins or small pain relievers and iced different parts, but recently I found something that works twice as good: tincture of arnica.
I had a bad fall and was literally swollen from head to toe, my boss put some of that stuff on the worst parts and after resting on the couch for a couple of hours I felt better than any time I used asprin or the like. I've used it several times and trust me- it's worth it! It's not a gimmick or a hoax it's the real deal in the herb stores. :)
Everyone falls and it's natural to be scared or intimidated but just remember: that was then and when your on the ground staring at your horse - that's now. Push through and shrug it off (you can get checked by a doc later
) get on the horse and prove to yourself that you can in fact get back on. Happy riding!
