Arm wrestling can produce arm injuries similar to trying to lift too much weight at the gym. Muscles, tendons and ligaments in your shoulder, arm and elbow are especially at risk of injury. Seek medical attention if you suspect a severe injury. Your doctor may take X-rays to check for bone injuries or request magnetic resonance imaging to examine the extent of the injury.
Minor Strains and Sprains
Strains and sprains are minor injuries that may produce pain after arm wrestling. Strains involve stretched or torn muscle fibers or tendons, and sprains involve torn or stretched ligaments. Grade-one injuries involve the least torn or stretched tissue, slight pain, slightly warm skin and little or no skin redness. Grade two injuries involve torn tissue and more pain, particularly when stretching or contacting the muscle. Muscles in your arm may feel swollen, and warm or hot to the touch. Pain and other symptoms for these injuries may last 24 to 72 hours.
Severe Strains and Sprains
Grade three strains and sprains occur when you tear most of the fibers in a muscle, or most of the ligament tissue in your joints. These severe injuries produce immediate and extreme pain. You may also experience prolonged heating of the skin, redness and swelling. The contour of your muscle may visibly change as a result of severe tissue damage. These injuries may completely eliminate or severely reduce muscle functioning in your arm.
Treatment for Strains and Sprains
Addressing strain and sprain injuries immediately after arm wrestling can prevent the injury from worsening. Let tissues in your arm begin healing by keeping weight off your arm. Applying ice for 15 to 30 minutes every two hours can reduce pain, redness and swelling. Gentile pressure with elastic bandages for 30 minutes can slow and internal bleeding and swelling. Elevating your arm six to 12 inches above your heart reduces blood flow and any internal bleeding. Severe injuries may require immobilization with a brace or splint. Your doctor may suggest surgery as a last resort for especially severe strains and sprains.
Fracture of the humeral shaft bone may be the most common injury reported in arm wrestling, according to a 2010 article by researchers at Germany's University Hospital Bergmannsheil. Fractures cause severe arm pain and immediate loss of grip strength. You may see changes in the contour of your arm, if you have a complete fracture. Your arm may feel tender to the touch, and you may experience coldness in your arms or hands, if blood supply is impaired. Fractures require immediate medical attention. Your doctor may be able to realign the broken bones without surgery, or she may apply nails and pins during surgery to hold bone fragments together.
