Back Pain Tips

Her left hind has a scar that you can feel as damaged tissue or muscle on the side of her thigh. She tends to have soundness problems in her left hock (made worse by her tendency to kick the walls), with a shortened stride or limp. Her back is unlevel, one side is noticeably lower than the other, so her saddle slips no matter how tight her girth is. She also keeps her tail clenched down very tightly, you cannot lift it up at all. The owner is not often around and I have been taking care of her. I’m fresh out of school, looking for work, and can’t afford to have anyone come look at her (neither could/would the owner!) Any ideas on how I can help this sweet horse???
