Most minor injuries will heal on their own, and home treatment is usually all that is needed to relieve your symptoms and promote healing. But if you suspect that you have a more severe injury, use first aid measures while you arrange for an evaluation by your doctor.
First aid for a suspected broken bone
If a bone is sticking out of your skin, do not try to push it back into your skin. It is better to leave the bone alone and cover the area with a clean bandage.
Remove all rings, bracelets, watches, or any other jewelry from the injured arm immediately. It may be hard to remove the jewelry if swelling occurs, which in turn can cause other serious problems, such as nerve compression or restricted blood flow.
Splint your injured arm without trying to straighten it. Loosen the wrap around the splint if you develop signs that indicate the wrap is too tight, such as numbness, tingling, increased pain, swelling, or cool skin below the wrap. A problem called compartment syndrome can develop.
If a cast or splint is applied, it is important to keep it dry and to try to move the uninjured part of your arm as normally as possible to help maintain muscle strength and tone. Your doctor will give you instructions on how to care for your cast or splint.
