So the vet has been out a couple times in the past week. My retired mare 16 yr old TB off the track suddenly became very sore and stiff. There was no incident, no swelling, no signs of anything. She is eating drinking everything else normally. She is stiff and sore in most of her body even with Anafen( pain med/antinflammatory and bute.We have run full bloodwork, ultrasounded, treated with antibiotics with no improvement. If anything she's worse! The vet is coming back out tomorrow. I was just curious if anyone has seen anything like this.
