My gelding somehow got hurt. I noticed he was stiff/ short striding on his left rear. Upon further inspection I found a huge knot on his hindquarter. It is tender to run your finger down it. It has some hard spots on it.  Still feels warm to the touch.

So I gave him bute and put DMSO on it. Figured he got kicked or something and it will go away.  I have also cold hosed it.  I have done all of this for over two weeks.

He has had limited turn out due to our boarding situation.  I have talked to a couple vets, they seem to think he just got kicked.

Now I am worried because it has gone on so long. I plan on getting him an appointment with a very good lameness vet when he comes back to the area.

When I was putting the DMSO on it last night, he acted like it hurt, but also itched. I lightly scratched it through the glove. He loved it and was mutual grooming the horse in front of him.

What could it be? A kick that won't heal? Turn into an abscess? A pulled muscle?? Its driving me crazy not knowing. I can't wait to get him into Dr Ford.

Since you said he was itchy in that spot and warm to the touch I kinda thinking he got kick and abscessed.. 

I'm hoping abscess instead of a muscle tear or something. My mind goes to worse case by default.

It was what the vet called a Sterile abscess from a shot he got a couple months before. He had cut his eye lid and needed it stitched back. I'm not for sure what the vet gave him back there. ( I was holding the twitch) 

But the vet seems to think it will heal just fine. Apparently these types go deep and take a long time to surface.

He's allowing me to dr on it without kicking my head off. It must feel so much better! 

Find someone in your area with a PEMF machine and get him a treatment (or sev). It increases blood flow/oxygen to the injured area. It will increase the healing and cut his time off by up to 1/3. He will let you know what is comfortable but IMO that would be the best thing esp since the vet said it was a deeper injury

I am looking into it! Thanks for the suggestion!
