I have an old gelding(20-ish) that had an abscess blow out under his hoof. I have been soaking with epsom salt, putting ickmenthol, and also so thrush remedy and wrapping it up and putting a boot on him. I didnt see where he was getting better so I had the farrier out to look at it and trim his hooves. Now he is even more lame than he was before. He doesnt want to put any weight on the hoof even with the boot on. Should I get a vet involved or should I just wait it out? This has been going on about 2 weeks now. The farrier came tuesday. Here is what his hoof looks like now.
