There are numerous reasons that could be contributing to your arm pain. Frequently, arm pain is caused by a muscle strain, a ligament sprain, tendonitis, a rotator cuff injury, or carpal tunnel syndrome. A muscle strain or ligament sprain can occur due to overuse or injury. Tendonitis frequently occurs at the elbow or wrist and is often due to overuse. For example, using a hammer for long durations involves the constant use of your elbow. This can lead to an aggravated and inflamed tendon, causing arm pain. A rotator cuff injury can cause pain to radiate down the arm – such as numbness, weakness, or a dull aching sensation. Carpal tunnel syndrome may create arm pain at the wrist.
Another, often overlooked, cause of arm pain is angina or a heart attack. If you are experiencing sudden pain in your left arm, have shortness of breath, dizziness, and chest pain, call 911. Get immediate medical help – it could potentially save your life.
