People complain of a couple of different things.
Active people complain of pain on the top of their shoulder when lifting their arm. When I ask them to lift their arm, it doesn’t really hurt until their elbow gets level with their shoulder and the tip of the shoulder begins to rotate upward. This is the point that the middle trapezius really engages. Sometimes they will produce the pain by wiggling around their shoulder until they lift it up toward their ear. They also complain of pain during exercises that lift their arm above their head as that also rotates the scapula upward.
People who carry something with a strap over the shoulder have tenderness on that spot where the bag presses into the shoulder. They will shift their purse, baby bag, travel bag or yoga bag to the other shoulder and smile as they tell me that the bag is probably causing the problem. This doubly aggravates this spot as it presses into the trigger point while the trapezius is rotating the shoulder up to keep the bag in place. People with a backpack may carry it by the strap or just put it on one shoulder.
People may also complain of a heavy coat that rides their sore shoulder, leaving them irritated. Children with sensory processing disorders may complain that they “just don’t like” their coat or backpack.
Obviously, stop carrying that bag on that shoulder until you get this fixed. But like my post on Cute Shoes, and my post on The Investors, I really think we should get our bodies working better to improve the quality of our life instead of continuing to age by limiting our choices.
You can reduce the inflammation here with an ice pack but the latent trigger point will not go away until this is area is worked, the tendons are released and the acromioclavicular joint is balanced.
This area responds well to direct work after taking care of cervical fixations and distracting the acromioclavicular joint. This is one of the few areas where I use a T-bar on a trigger point. The tendon of supraspinatus and biceps brachii are almost always in need of some direct work for lasting results. People don’t usually complain about this until other muscles have become involved.
The trigger point in lower trapezius is most often confused with this trigger point. The lower trapezius trigger point is less common. This trigger point is more common and produces the upper neck tension from other trigger points, usually involved with forward head posture.
