My mare has a huge swelling on the front of her chest on one side. She lives out with two horses so it is possible she has been kicked. The vet was out and thinks that's the most likely cause. There is no heat in it and it appears to be very firm to touch, doesn't feel like an abbess. We trotted her up and she doesn't appear to be lame or sore and is acting normally. She was vaccinated 2 weeks ago but vet doesn't think its a reaction. She has been in the field for 2 weeks, I have been checking her but never got taking her in to check under her rug until yesterday so not sure when the swelling occurred. The vet says if it is a kick, because it is cold and is firm it may be a swelling on the bone/muscle that may never go down. Any advice or common experiences of this would be greatly appreciated. Thanks
