Remove all bracelets and rings. It may be hard to remove the jewelry if your arm or hand swells. Swelling without removal of jewelry can cause other serious problems, such as nerve compression or restricted blood flow.
Do not try to straighten the injured arm. If a bone is sticking out of the skin, do not try to push it back into the skin. Cover the area with a clean bandage, and use a splint to support the arm in its current position.
Splint an injured arm to protect it from further injury. Loosen the wrap around the splint if you have numbness, tingling, increased pain, swelling, cool skin, or other symptoms. The wrap may be too tight.
If your arm is in a cast or splint, your doctor will give you instructions on how to care for your cast or splint. Try to move the uninjured parts of your arm as normally as possible to help maintain muscle strength and tone.
