So I put Kiara to the stall for the night. She was fine yesterday night. And this morning when we let her out she had issues moving her back feet. Not lame or anything, but looks extremely stiff with the hind. The best comparison would be if you sit on one leg without moving for really long time you have the same issues: hard to move, don't feel it, and then the pain kicks in.
So I started to walk her back and forth and after 5 mins I lightly trotted her and she looked OK (although little stiff). She ate her grain with great appetite (as usual) and she was busy with the hay when I left. Mom checked on her hour later and said she drags one leg again a little. She gave her massage and it was OK again.
So my question is... Any ideas on what could it be? Could it be that no movement in stall for while could bring this problem up? Can it be EPM (I'm REALLY scared of that)? She has that bump between the front legs, so I think that may be after hot compress she felt pretty good and warm, fall asleep and stayed there for too long...?
Anyway, I called my vet and he said to watch her till tomorrow to see what will happen. And I definitely won't put her in stall for while too.
