My mare got her vacs for tetanus and flu three days ago. She is still very careful to move her neck and doesn't want (or does it very slowly) to reach hay or grass on the ground. I put hay in hay net and get it up so she can eat without problems. She has a lump where vet put needle in and the muscle is swollen and warm. It's the third day today and it doesn't seem to be going better. I'm cooling down the area, is this ok?
When should she be okay? When to call a vet?
She eats, drinks and seems pretty normal otherwise, she even charged at pony today. Once she has her head down she grazes normally.
