Tucker's hock is still swollen after a week of poultices.
My vet was out again yesterday. He is very puzzled. He did an ultrasound and did not find any damage to ligaments or tendons. There was a lot of fluid in the joint capsule area.
He drew some of the fluid out and took some to culture for an infection.
However, he just called to tell me there was no sign of infection in the blood or serum.
So, we are still sort of at square one.
Tuck is on one gram of bute a day and a Volteran rub on the hock for now. He is confined to the stall and a very small run-in shed area...about 10' X 24' to keep him from running around. It's better than just stall confinement and it's on the shady side of the barn.
My vet has sent the X-rays to a surgeon he knows to see if there are any other suggestions for treatment.
The hock is not quite as swollen as it was, but it is certainly not normal.
The adventure continues. (I might see if I can get some pictures to post.)
