What is shoulder stiffness and neck pain?
Shoulder stiffness and neck pain are often referred to as a "national ailment of modern people," with surveys from the Ministry of Health, Labour and Welfare showing that they are the most common complaint among women and the second most common among men. While primarily caused by poor posture and muscle tension due to increased desk work and smartphone use, cervical spine diseases, nerve compression, and internal medical conditions can also be underlying factors.
At our clinic, we evaluate the involvement of cardiovascular diseases, thyroid diseases, and rheumatism from an internal medicine perspective, distinguishing whether it is merely a muscle issue or a sign of a systemic illness. We collaborate with orthopedic and neurosurgical departments as needed.
Shoulder stiffness that should not be overlooked
Shoulder stiffness accompanied by the following symptoms requires attention: suddenly intensified, accompanied by numbness/weakness, fever, weight loss, or severe headache. These could indicate cervical spine disease, myocardial infarction (referred pain), meningitis, or tumors.
Main Causes of Shoulder Stiffness
Musculoskeletal System (most common)
- Muscle tension in the trapezius and levator scapulae
- Poor posture (hunchback, straight neck)
- Prolonged desk work/smartphone use
- Eye strain
- Coldness/poor circulation
- Mental stress/tension
- Lack of exercise/muscle weakness
- Inappropriate pillow/bedding
Cervical Spine/Nervous System
| Condition | Characteristics |
|---|---|
| Cervical spondylosis | Age-related cervical spine deformation/osteophyte formation |
| Cervical disc herniation | Worsens with neck movement, arm numbness/weakness |
| Cervical radiculopathy | Pain/numbness in dermatomal distribution |
| Cervical myelopathy | Fine motor skill impairment of fingers/gait disturbance |
| Thoracic outlet syndrome | Arm numbness when raising arm |
| Straight neck | Loss of physiological curvature of the cervical spine |
Internal Medical Conditions (not to be overlooked)
| Condition | Characteristics |
|---|---|
| Angina pectoris/myocardial infarction (referred pain) | Worsens with exertion, widespread pain from left shoulder to jaw |
| Hypothyroidism | Swelling, fatigue, shoulder stiffness, weight gain |
| Polymyalgia rheumatica | Morning stiffness in both shoulders and lower back, over 50 years old |
| Rheumatoid arthritis | Polyarthralgia, morning stiffness lasting over 1 hour |
| Hypertension | Stiffness from back of head to nape of neck |
| Anemia | Appears with fatigue |
| Menopausal disorder | Shoulder stiffness + hot flashes, sweating, mood swings |
| Depression/autonomic dysfunction | As part of chronic systemic symptoms |
Eyes/ENT System
- Eye strain/vision loss
- Strabismus/hyperopia/presbyopia
- Sinusitis
Symptoms to Watch Out for with Neck Pain
The following symptoms require attention
There is a possibility of serious illness. Prompt medical attention is necessary.
- Fever + neck stiffness (suspicion of meningitis)
- Severe neck pain after trauma (cervical spine injury)
- Accompanied by arm numbness/weakness
- Difficulty walking/fine motor skill impairment of fingers
- Bladder/bowel dysfunction
- Accompanied by thunderclap headache (suspicion of subarachnoid hemorrhage)
- Referred pain to left chest ~ left shoulder ~ left jaw (myocardial infarction)
- Swollen lymph nodes in the neck
- Persistent pain accompanied by weight loss
- Pain that worsens at night
About Straight Neck
"Straight neck" refers to a condition where the cervical spine, which normally has a gentle forward convex curve, becomes straight due to smartphone or PC use. The cervical spine cannot absorb impact, leading to shoulder stiffness, neck pain, and headaches.
Straight Neck Self-Check
- When you stand with your heels, buttocks, shoulders, and back of your head against a wall, your head does not easily touch the wall.
- You spend a lot of time looking down (smartphone, reading).
- You have prolonged desk work.
- Your pillow doesn't fit, and your neck hurts when you wake up in the morning.
- Your head is forward of your body (forward head posture).
About Cervical Radiculopathy
Cervical radiculopathy is a condition where nerve roots are compressed due to age-related changes in the cervical spine, characterized by pain and numbness on one side of the neck, shoulder, and arm.
Symptoms
- Pain radiating to the arm when extending or turning the neck
- Numbness/pain in one upper limb (dermatomal distribution)
- Muscle weakness/decreased reflexes
- Muscle atrophy in severe cases
Diagnosis
- Positive Spurling's test (referred pain with neck extension and compression)
- MRI (performed by orthopedics)
- Nerve conduction study
Treatment
- Conservative treatment (NSAIDs, cervical collar, physical therapy)
- Neuropathic pain medication
- Nerve root block (orthopedics, pain clinic)
- Surgery for intractable cases (anterior decompression and fusion, etc.)
Don't Miss Referred Pain from Myocardial Infarction
"Just shoulder stiffness" could be heart disease
Myocardial infarction pain can spread not only to the chest but also to the left shoulder, left jaw, left arm, and back. If the pain worsens with exertion, is accompanied by cold sweat, shortness of breath, or is a strong, new shoulder pain, suspect a cardiac origin and seek prompt medical attention.
Symptoms Requiring Emergency Attention
- Shoulder or chest pain that worsens with exertion or stress
- Severe pain lasting more than 20 minutes
- Accompanied by cold sweat, nausea, or vomiting
- Shortness of breath/difficulty breathing
- Blurred consciousness
- Widespread pain predominantly on the left side
Consultation and Examination
Medical Interview
- Onset and duration of symptoms
- Location and nature of pain/stiffness
- Accompanying symptoms (headache, numbness, chest pain)
- Work/lifestyle habits (desk work, smartphone usage time)
- Medical history/family history
- Current medications

To prevent chronification, act early
If shoulder stiffness is left untreated as "it will get better eventually," it can become chronic and reduce quality of life with headaches, insomnia, and decreased concentration. Most cases improve when the cause is identified and properly addressed. Please feel free to consult us if you are concerned.
