Arm back to back, shoulder blades on both sides are different, one is normal and the other is very big. What's the reason
These two shoulder blades do look a little different. I don't know when you have this situation. If you have been like this since childhood, it should be a developmental abnormality. A few people have different sizes of shoulder blades. This kind of situation is generally difficult to treat. You first have a chest CT to see the severity.
