What’s causing the pinching in my shoulder?


About 5 months ago, I was diagnosed with tendinosis and an interstitial tear in my right shoulder. Since then, I have gone through and completed physical therapy — improving my range of motion and being pain-free. Since I have been discharged, I have been continuing my exercises at home, but have recently noticed an issue with my shoulder blades/scapula. When my back is flat against something like a chair or a bed, I feel a “pinching” discomfort in my left shoulder blade, however there is no winging or sticking out present here. My right scapula, however, is sticking out more than the left. I don’t feel any of the pinching or discomfort in my right scapula, so I was wondering what this could possibly indicate. I was wondering if it’s also possible that the right scapula is actually normal, and the left is somehow inverted instead of protruding like a regular winged scapula. Is it possible I’m having a protruding winged right scapula and a pinch/thoracic nerve compression of the left scapula with no visible indications at the same time?

Things to Know

  • After shoulder rehab, it is not uncommon for body parts above or below the shoulder, to compensate and contribute to symptoms and pain.
  • Asymmetries are normal throughout the body, but they should not cause pain or functional limitations.
  • It is normal to experience some discomfort with exercises in the presence of tendinosis.

Thank you for your question! Without doing an examination, we are not able to comment on your specific condition, however, we can offer you some general advice that is often helpful in similar situations to yours.  

There are a few potential explanations for your symptoms. Depending on the location of your tendinosis and interstitial tear, it’s possible lingering deficits in strength, stability and control of your shoulder and shoulder blade could contribute to your shoulder blade positioning. If present, this can greatly influence the position of your humeral head relative to the joint surface during movement, exercises, and in static positions, potentially resulting in discomfort and “pinching” sensations. 

Tightness in muscles and other joints that surround and comprise of the shoulder girdle could also be contributing. If these types of restrictions do not allow an appropriate amount of movement, then this could also impact shoulder positioning and symptoms. 

It is also very common for the neck to refer pain into the shoulder and/or shoulder blade and could be contributing to the symptoms you are experiencing. This could include joint or muscle referral pain to the shoulder blade or could be a nerve referring the pinching sensation to that region. With your history of recent rehab for your shoulder, it is not uncommon for body parts, above or below the affected region, to compensate or be affected and it would be beneficial to seek further re-assessment to assess your neck as a possible contributor to symptoms.

It’s quite possible you could be experiencing scapular winging and pinching discomfort at the same time. Asymmetries are normal throughout the body, however, if these asymmetries begin to cause pain and functional limitations, then it’s important to address them accordingly with a referral to physical therapy. 

It is normal to experience some discomfort with exercises in the presence of tendinosis as long as your symptoms do not exceed a 4/10 on the pain scale and soreness does not last longer than 24 hours following your exercises. Additionally, even with a comprehensive program, if exercises are not completed correctly, they may contribute to some of the discomforts you are experiencing. If you continue to experience symptoms, you should schedule a follow-up with your physical therapist or consult another practitioner.
