After speaking with DVME today, I feel somewhat better - and I use the word somewhat very hesitantly - about what our next step is with Chester. In a nutshell, we are going to hold off on the imagery for now - partly to save my wallet and having to refinance our house - and partly to try and isolate the problem area. She keeps going back to his hoof, I keep giving her slack about it.
ME: DVME, you're telling me he can spook and have his hoof be the cause of his lameness?
DVME: I've had a couple handfuls of cases where horses have spooked and pulled tendons and torn ligaments in their hoof. Carrie, do you know how many different things can go wrong in there?
ME: Yes, DVME, there are about a quadrillion things that can go wrong in there. (sighs audibly)
On Monday, she is going to come on out and we are going to nerve block his hoof.
What are nerve and joint blocks?
Nerve and joint blocks involve the injection of a local anaesthetic (Lidocane anyone?!!) either close to a nerve or directly into a joint or into another synovial cavity, such as the navicular bursa or a tendon sheath. The local anaesthetic temporarily disrupts the function of any nerves or nerve endings it contacts. This results in areas of desensitisation (numbing). The desensitised area depends on which nerves or nerve endings are affected. Thus, if the local anaesthetic is placed around a nerve, such as the palmar digital nerve that runs down on both sides of the back of the pastern before entering the foot, the areas supplied by that nerve will become desensitised. If the horse has pain in this area, the nerve block will temporarily numb it and the lameness may disappear. These blocks are used as one part of an examination of the lame horse. Usually, the horse is trotted up (either in a straight line on a hard, level surface and/or on the lunge in both directions), and the degree of lameness is noted. The block is then applied and the horse trotted up again to see whether there has been any improvement in the degree of lameness. If the lameness has improved, it is likely that the site of pain causing it is situated in the area of the foot that has been desensitised by the block.

I still believe in him. And you can bet your ass I'm not going to quit.
