It can cause aching, burning, or sharp pain in the back of the shoulder, and may contribute to discomfort or restricted movement in the shoulder and arm.

• Potential Causes

• Overuse or repetitive activities involving external rotation and adduction of the shoulder, such as throwing, swimming, or certain weightlifting exercises.

• Poor posture, especially rounded shoulders.

• Muscle imbalances between the teres minor and other shoulder muscles.

• Trauma or injury to the shoulder or upper back area.

• Prevention Tips

• Use proper techniques and form during shoulder exercises to avoid overloading the teres minor.

• Incorporate regular stretching and strengthening exercises for the shoulder muscles.

• Ensure proper warm-up and cooldown routines before and after exercise.

• Maintain good posture and ergonomics during daily activities.

• Ensure balanced strength training to avoid muscle imbalances.
