So I am going to get more aggressive with my treatment and try really hard not to screw it up any more.
In the mean time I went just to check on him yesterday. I brought him in from the paddock, just to groom him. And then I noticed his Left Stifle was banged up. Not severely, but maybe like he ran into something and scraped off some patches of hair and maybe a slight abrasion. Then, working down the leg noticed the lower leg and fetlock were swollen and there was a scrape/puncture on the cannon bone. He trotted off fine (I had the BO do the trotting... see, I'm TRYING not to hurt myself) but I gave him some bute and cold hosed the leg. He didn't appreciate me poking the stifle but he never really does. I'll go out today but then I'm benched for the weekend after I'm going to have a needle inserted into my spine. Ugh.
So I recruited the BM to keep a closer eye on him over the weekend. I might be able to go out, but I really need to be careful.
Of course he mildly injures himself when I can't monitor it. Sometimes I think he plans things like this.
