Well, for me it was more an anatomy issue. Unknown to me, my acromion is thicker than normal. Each time I’d raise my arms over my head impingement would occur at the RTC. Over many years of yoga practice I developed micro tears in the Subscapularis and supraspinatus tendons. Micro tears led to bigger tears. One was a full thickness tear and the other was a partial. Needless to say, I ended up having it repaired. Through PT and yoga I am 100% today. My left shoulder(repaired one) is stronger than my right. Same issues going on in my right, so surgery is likely in my near future. But what helped me the most was Down Dog. After my surgery, the first time during my PT sessions that I was allowed to get into that pose, I felt the my whole back side lengthening, the scapulae moving and heavens it felt great!
So I guess my point is sometimes we are doing poses correctly, but due to anatomy issues (often times unknown to us) those correctly done poses are actually harming us. The only way to find out is unfortunately through injury.
