I recently switched my horse to a new boarding facility a couple weeks ago. He was turned out with a bunch of geldings to run and play with which he was not used to. A couple of days ago I was grooming him and preparing to saddle up so I checked for any back or leg soreness (like I always do before I ride) and I noticed he was flinching and tensing up when I would run my hand down is right side and down his back leg. He became very agitated and stressed from the pain so I called one of the barn managers to check him out. She noticed that the upper part of his right back leg was very tender and she told me not to worry and that it was probably from him playing a little rough with the big boys out in the pasture. I haven't been riding him for the past couple days but I do put his halter and lead on him and walk him around the arena for about an hour a day. I checked his leg again today and it still seems sore. Is there anything I can do for him besides walking him and letting his leg work the soreness out on its own? I have given him some mild pain meds at night so he can sleep better but honestly he doesn't seem in pain as long as I don't touch his leg... Is there anything I can do for him? Or am I doing all I can? Thanks!
