How People Describe This Pain Pattern
People complain of pain that disturbs their sleep when lying on the painful shoulder or the opposite shoulder. It is a deeper pain than the illustration suggests. They have spent most of their time sleeping on that shoulder with that hand in front of them. It usually comes on gradually over months and eventually gets difficult to ignore.
Often, the afflicted have tried many sleeping positions and would just like to get back to sleeping on their side, which is most restful.
Other symptoms are common but not always present, The grip is weak on that hand, and they have learned to be careful with things like a coffee cup. They may have pain in the back of the neck but usually don’t complain about it first. They may also have pain when reaching high overhead.
How You Activate and Intensify This Pain Pattern
Tucking in a shirt or reaching to the back seat is painful and aggravates the trigger point. It can be sharp when you extend their arm out to put something on the nightstand.
This pain pattern may come on quickly when there is a trauma to the shoulder. Common incidents include when the shoulder gets twisted against the front of the body in a fall. The shoulder may also get overstretched by a dog that jerks the shoulder forward on a leash.
If the trigger point is already mildly aggravated and the shoulder joint is binding, it can be intensified by reaching back suddenly or having the arm forced back. This can also happen when catching yourself in a fall or reaching back quickly to attend to a child in the car.
The trigger point is activated at night because sleeping on that shoulder has chronically pushed the humerus in the shoulder socket, and the muscle has tightened to stabilize the shoulder. It’s just a trigger point doing its job.
Testing to Assess the Trigger Point
These tests will produce pain and restricted motion when the trigger points in the infraspinatus are active.
The first test involves placing the forearm across the low back. It usually produces pain in the shoulder. Pain worsens as you reach up the middle of the back. Notably, this may also indicate trigger points in the coracobrachialis with a different pain pattern.
In the second test, reach around the back of your head like the pic. When the trigger points are active, it is restricted and painful. Also, you cannot contact the edge of your mouth without pain and stiffness.
