Well the cortisone shot didn't last too long. I just left him in the vet for some blood work and x rays. When I went home for lunch he yelped when I tried getting him out the crate and he is in slow motion like takes him a long time to get out of the crate. He's eating great, pooping regularly so I'm just baffled. He was shaking a little on the way to the vet. It's so weird, even going outside and not picking up leaves and wood sticks like he used to, or chewing or playing w/ his toys. I will find out in a few hours.
