My vet was baffled and called out a horse specialist, meanwhile he gave her a small cortisone injection to relieve possible swelling in her brain.
When the second vet arrived just over 1 hour later she was fine and there has been no recurrence. We have no idea what the problem was, any ideas?
Vet thought maybe she had hit her head but no tenderness anywhere, or possibly a small stroke.
Nothing toxic in her field and no contact with other horses recently or signs of her struggling anywhere.
