In theory - yes, diazepam is a benzodiazepine and in the same class of drugs as Xanax, so it will stop all sorts of things -- the bigger concern is why you are having leg tremors. Are you referring to Restless Leg Syndrome - I would never prescribe Diazapem for that. If they are recent on-set you need to speak to a physician, but Diazepam is not indicated or labelled for RLS use/treatment. At least, not last I checked - I could be wrong.
Well it would die
Take it to the vet, this would be the safest thing to do.
I would imagine soap would help that, clean it as much as possible with soap as well.
Giving someone a leg up is when you help them
You can put ice or heat on your leg, this will help with your swelling.
Well, from my knowledge, they had a tool called a Leg Splint. It was a wooden thing that would attach to your leg. If you were in need of a leg splint, some would just chop off a tree branch and use that. Many infections and such things as the Leg Splint were what caused disease and other infections. I'm glad we have good medical services and ways to help our legs and NOT use Leg Splints.
Leg bones are the bones in your leg and they are the things that help you walk.
No. Even with the affected limb amputated ... the person would still feel phantom pain. As though the leg is still there.
The outside leg is the leg "on the fence" when going around the ring. So, if the horse is traveling clockwise (to the right) around the ring, the rider's outside leg would be the left leg and her inside leg would be the right leg.
No.
Stair steppers would help you tone up your thighs. Also leg presses would be beneficial. When you are at home and don't have machines to use, squats and wall sits can help out.
It depends on what kind of injury. Bell Boots would prevent injury to the hooves. So would shoes. And leg wraps would prevent injury to the tendons in the lower leg. But like I said, it depends on what kind of injury you are triyng to prevent.
