Hi, my horse is very sensitive to touch (when I brush him etc.) in the area between the hip and flank - closer to the hip but where the hair grows in the different direction (not sure if this area has a specific name). I have had him 12mths and he has always been a little sensitive in that area on both sides when grooming (even though I am extremely gentle around there) but recently he has been kicking out his back leg in response. I had the chiropracter out to him 1 week ago when he first kicked out , and he had a few sore spots along his back in the hip region but it hasn't helped his reaction in this area.
He also scours a lot when he is out on rich grass - I didn't worry too much as the other horses reacted like this to the ridiculous amount of spring grass in one particular paddock we had but now it is Autumn, there is still green grass underneath the dry in the paddock, but I thought it couldn't possibly a rich as it was in spring and yet if I let him into that paddock - he is scouring after 1 day.
He is 23 but still going strong in most ways.
There have been a couple of times riding when he's dropped his back leg simultaneously, only on gravel - never on grass - it was never enough to worry me but considering his sensitivity now, I'm wondering if this may be a sign of something
