What is the difference between cervical spondylosis and shoulder pain?

The presentation of different types of cervical spondylosis is different and can be well identified by the general clinical presentation of cervical spondylosis and frozen shoulder.
Cervical cervical spondylosis mainly causes painful stiffness in the neck, which may be accompanied by pain in the shoulder joint, but the limitation of movement in the shoulder joint is not very severe at this time.
Neurogenic cervical spondylosis causes pain in the shoulder joint and radiating pain in the upper limbs, but the pain in the shoulder joint does not cause numbness and the limitation of movement in the shoulder joint is very severe.
Spondylotic cervical spondylosis does not affect the shoulder joint, so this is well differentiated from shoulder pain.
A cervical magnetic resonance imaging (MRI) examination should be perfected to be able to effectively differentiate.
