Help!! Possible Abscess blocking urine

I have a weathered goat that is approx 4 months. He is nibbling hay, I have held back grain. Put my thumb in his mouth which seems a little cool to me. he has a wide stance In back legs and what seems to be a large hand size abscess on his scrotum area. I do not think it is calculi but he is not able to pee, barely a trickle. No teeth grinding, is standing and will move away from other goats-he is now separated. We are in the lowcountry of SC and there is literally only one vet, a mobile vet, that is tied up what may be all day. I am looking for advice.

 

There are only two vets that treat goats in my area within a three hour drive!!! They are mobile vets and neither could come
However, I did speak to one and sent pics. He thinks he has tetanus I have only had this little fella three weeks. They breeder says he used CD&T vax but not tetanus when he banded him. The vet told me to give him PennG 3 times a day and see if he responds but told me if it was tetanus it was fatal He is still with is 24 hours later but has quit eating and has started teeth grinding

 

And here is an attempt to load pics!

 

his output has been a slow trickle. He is 4 months old. He was banded and completely healed before I got him- you will notice that his testicles ae gone. I do not see any break in the skin. As I mentioned, I do not believe it is tetanus personally, just relaying what the vet said.

 

The pics were taken right after I found him in his condition yesterday. The swollen area was very hard and felt like an abscess of some sort. After I separated him and he settled down he laid down and got relaxed. I was then able to go out and turn him on his side and get a better look at the area. The swollen area seemed to have dispersed, it was no longer localized and concentrated in that area. As i felt along going towards his his rear i could feel knots and the area seemed to harden the further back i went and down into the inner thigh area.
And you are asking questions faster than i can answer lol, however, I appreciate your input.

 

I have never in 9 years of “goating” had to deal with UC and never heard of it in such a young goat that is not heavily grained especially but I did have a friend recommend another goat friend experienced in such matters since I cannot get a vet out here
