Shoulder pain isn't necessarily caused by frozen shoulder! Frozen shoulder primarily manifests as shoulder and arm pain with limited movement, characterized by worsening pain during quiet periods at night. While receiving treatment at an orthopedic hospital, actively pursue adjunctive therapies to facilitate faster recovery. However, not all shoulder pain stems from frozen shoulder. The following conditions also commonly cause shoulder pain—never be complacent and risk delaying proper diagnosis.
Case Study: Shoulder Pain Not Necessarily Frozen Shoulder
Mr. Li, a fifty-something cadre at an organization, primarily handles administrative work. An avid player of badminton and table tennis, he has always enjoyed good health.Over the past two years, he has been troubled by recurring pain in his right shoulder joint after movement. Initially, he attributed it to work overload and overexertion during sports. However, the pain persisted even after a week of rest. Hospital imaging revealed "cystic changes in the greater tubercle of the humerus, with no abnormalities in the glenoid fossa." The doctor diagnosed it as "frozen shoulder."
To treat this frozen shoulder, he visited several hospitals over two to three months, undergoing massage, physical therapy, and medication. He also performed daily exercises like wall climbing, pendulum movements, and combing his hair, yet saw little improvement. He constantly felt weak when lifting his shoulder, and the nighttime pain became unbearable, severely impacting his work and daily life.Finally, a physician conducted a thorough physical examination and ordered an MRI. It turned out Old Li didn't have frozen shoulder but a "rotator cuff injury." He underwent shoulder arthroscopy surgery, and his symptoms were well-controlled post-operatively. He fully recovered within three months and resumed playing badminton six months later, significantly improving his quality of life. So, what other conditions can cause shoulder pain? Cholangitis.Sensory nerves in the gallbladder and right shoulder overlap, so gallbladder inflammation can cause dull pain in the right shoulder and scapular region. If shoulder pain is accompanied by recurring heartburn, belching, acid reflux, bloating, or nausea, don't overlook gallbladder issues. Ultrasound can confirm the diagnosis, and shoulder pain may improve with anti-infective, antispasmodic, and analgesic treatments.
Angina Pectoris and Myocardial Infarction. Pain from myocardial ischemia may radiate beyond the precordial area to locations like the left shoulder. Angina is often triggered by exertion or emotional stress and typically subsides with rest. Myocardial infarction frequently occurs during sleep or rest, often accompanied by severe symptoms such as pallor, profuse sweating, shortness of breath, and heart failure.Individuals with a history of coronary heart disease should be especially vigilant.
Cervical Spondylosis. Neck and back soreness, along with limited neck mobility, caused by cervical spondylosis are often due to compressed and irritated nerve roots. This typically presents as an electric shock-like sensation, accompanied by finger numbness, cold limbs, and abnormal skin sensations in the area supplied by the compressed nerve. However, there is no impairment of shoulder joint movement.
Shoulder joint tuberculosis. Both shoulder joint tuberculosis and frozen shoulder present with shoulder pain and functional limitations. However, shoulder joint tuberculosis develops gradually and is often accompanied by systemic symptoms such as afternoon low-grade fever, night sweats, generalized fatigue, pallor, and a rosy flush on the cheekbones. X-ray imaging aids in diagnosis.
Shoulder Tumors. Tumors around the shoulder may cause shoulder pain or functional impairment in the shoulder and arm as they grow. Unlike frozen shoulder, the pain gradually intensifies, and the painful area expands as the tumor grows and causes local swelling. X-rays aid in confirmation.
Biceps Tendonitis and Tenosynovitis.Unlike frozen shoulder, although both involve anterior shoulder pain, patients often have a history of minor trauma such as shoulder pulling or twisting, or overuse. Some patients develop symptoms after exposure to cold drafts. Pain may radiate to the upper arm and neck.
Simply put, shoulder pain is primarily caused by two factors:
I. Shoulder-related causes:
1. Primarily affects middle-aged and elderly individuals over 40, where degenerative changes in soft tissues reduce tolerance to external forces;
2. Chronic stress from prolonged overuse or poor posture serves as the main trigger;
3. Prolonged immobilization after upper limb trauma leads to secondary atrophy and adhesions in shoulder tissues.
4. Improper treatment following acute shoulder contusions or strains.
II. External factors:
Shoulder referred pain from cervical spondylosis, cardiac, pulmonary, or biliary tract diseases. Persistent muscle spasm and ischemia in the shoulder due to chronic underlying conditions can form inflammatory foci, evolving into true frozen shoulder.
How to treat shoulder pain? Try these exercises:
1. Touch your shoulder with your fingers, then rotate your arm in a "米" shape (front and back);
2. Extend your arm straight and swing it vigorously back and forth;
3. Keep head upright, slowly raise shoulders toward ears, then lower gradually. Repeat multiple times;
4. Place palms on waist and attempt backward walking to strengthen back muscles;
5. Hold onto a table, twist waist left and right, then perform leg kicks up and down.
