If you have pain in your shoulders, then you might consider doing Gua Sha on it. It works particularly well on any impinged or tight shoulders (i.e. frozen shoulders). Many people have used the Flowstick on the rotator cuffs and seen great results.
For those who are not familiar with the rotator cuffs, here’s a brief introduction:
What is the rotator cuff?
The rotator cuff is a group of tendons and muscles that support the arm at the shoulder joint. They provide stability and allow the arm to rotate horizontally and vertically.
There are 4 muscles that make up the rotator cuff, and each of them lie underneath the bigger muscles (deltoids, trapezius and pectoral). The 4 muscles can be remembered easily by the acronym SITS.
S – Supraspinatus
I – Infraspinatus
T – Teres Minor
S – Subscapularis
Here is an excellent video that will help you visualize each of these muscles:
How to do Gua Sha on the rotator cuff?
Gua Sha is extremely effective on the rotator cuff. As with any injury, in addition to the pained/tight area, look upstream and downstream to it. In this case, upstream would be the neck, and downstream would be the latissimus dorsi (lats).
Start with the neck and work your way across the shoulder. Slowly go lower down into the shoulder blade and find points where the skin starts to show bright red spots. This is the petechia forming and is a sign that the area needs treatment.
Keep working your way down into the lats – again following the path of the red marks. If there are no red marks, then you can ignore that spot.
