Heaviness in the right shoulder blade that comes and goes and gets triggered with random movements can often be related to:
Muscular imbalance or spasm (common in rhomboids, trapezius, or rotator cuff muscles).
Postural strain (long sitting, laptop/phone use â upper back and scapular overload).
Cervical spine referral (sometimes a disc or nerve irritation in the neck refers pain/heaviness to the shoulder blade).
Scapulothoracic dysfunction (the way your shoulder blade moves over your ribcage).
Most commonly, this is musculoskeletal in nature, but the cervical spine should always be kept in mind as a contributing factor.
