Just remembering the time they put the shot on my asscheek instead of my thigh (I had anti rabies and anti tetanus no idea which one was shot on my ass )
Usually tetanus can be given in the arm and I only know rabies to be given into the stomach (except for the new pills.)
You could have gotten tetanus in the thigh or butt. It could have also been a fever-reducing, antiviral shot. All the shots I have heard of at the butt do something to that effect.
I'm not a nurse so I don't know exactly. My medical field doesn't deal with pills and shots; we just need to know of them and some for what they do for side effects.
When we saw the coyote bite, my first reaction was, "Rabies shot." Glad they brought that up but man, that's a brutal shot. And he's got to get them for months. They just came out with pills for it so fingers crossed the shot might fall out of style.
