Internal
A sprained ankle is a minor wound, but it's certainly not superficial, it is really a damage to the conjunctive tissue of the joint (usually the ligaments) imagine that your bones are held together at the joint by small wires and ropes which behave like rubber bands, when you twist a joint really hard, these rubber bands stretch and they swell causing pain, they will heal by immobilizing the joint, if they break, then it is not a sprain it is a ligament break and has to be fixed with surgery.
No, it can be sprained without being swollen.
It could be either sprained or broken, if in doubt get it checked.
If it is sore it is either just sore, bruised, sprained or broken.

If your hand is just sprained, it should heal in 7-10 days.
It depends on how badly your ankle is sprained.
You say: "Mom, can you take me to the hospital? I think my wrist is sprained."
you call it a leg that has been hurt not severely but maybe damaged somehow
Bones don't become sprained; muscles become sprained. Painful breathing can temporarily affect your health. It is important to have good pain control so that you can work to breathe fully.
A sprained ankle typically involves damage to the ligaments surrounding the ankle joint rather than a specific bone. However, in some cases, a sprained ankle can also involve a fracture in one of the ankle bones.
