The deltoid is a large muscle responsible for lifting the arm and giving the shoulder its range of motion.
It is located in the uppermost part of the arm, at the shoulder. Tendons attach the deltoid to the collarbone, shoulder blade, and upper arm.
Like many other muscles, the deltoid can be sore for a variety of reasons, including overuse and tendon injuries.
