Broken Bones or Sprains:
Sometimes a broken or fractured bone is obvious and other times it may be difficult to tell if a limb is merely badly bruised. When in doubt, treat for a broken limb. You should never try and reset the bone by yourself. Handle injured limbs with care to insure no further damage is done.
Leg or Arm: If the person must be moved, splint the broken limb by fastening it to two sturdy boards, poles, branches etc. The splint must be long enough to extend past the joint above and below the fracture. Pad the inside of the splint with soft material and tie the splint to the limb in at least three places. Do not tie it too tight oryo might cut off the circulation.

Sprains:
When the tissues, ligament, tendons and blood vessels surrounding a joint are stretched or damaged, the joint may be sprained. The body parts most commonly sprained include the ankles, fingers, wrists, and knees. A sprain is not always easy to tell from a fracture, but if you are certain it is a sprain, treat as follows:

1. Elevate the injured area by propping it with soft objects or in a sling
2. Apply a ice pack or another kind of cold pack to reduce pain an swelling
3. Leave it on ice for at least 30 minutes

If you are out in the woods and it is necessary to walk try this:
1. Untie the shoelaces to allow for swelling, but don't remove the shoe.
2. With a long bandage of handkerchief wrap the ankle.
Doing this will help support the ankle and make the walk less painful.
