A suprascapular nerve entrapment may cause the following symptoms: 1. There will be localized pain. This pain is initially manifested only as a dull pain in the posterior aspect of the shoulder joint or in the back of the shoulder. As the entrapment worsens, it may produce radiating pain to the surrounding area. For example, when pressure is applied to the posterior side of the shoulder joint, there may be some obvious pressure points, and if pressure is applied to it continuously, it may induce a sensation of discharge to the surrounding area. 2. There may be symptoms of restricted movement. Patients who present with this disorder are often reluctant to move one side of the shoulder, or even the entire upper extremity, because of the pain in the shoulder. If the shoulder joint on this side is moved passively, there is also a significant decrease in the mobility of the shoulder joint on this side. 3. There may be atrophy of the shoulder muscles. Patients who develop this type of nerve entrapment often show muscle atrophy around the scapula. For example, the trapezius, supraspinatus, infraspinatus and so on.
