Hi Brown Shugga,
Pain in the shoulder radiating up from the arm can be a symptom of a heart attack. Often the pain is associated with other symptoms such as chest pain or jaw pain, but it can stand alone. If this pain is unusual for you and you cannot link it to any activity that may have caused a pinched nerve, pulled muscle, or any other joint or bone pain, then you should see your physician. Even if it is not related to your heart, you may still require treatment for the pain itself.
Best of luck,
Monica M. Skidmore, MS, RD
