Stiffness in the shoulders and neck is caused by conditions such as myofascitis and cervical spondylosis. Remaining for prolonged periods in cool, damp environments or overworking can lead to strain in the neck and shoulder areas, resulting in cervical and shoulder myofascitis. Patients may experience muscle stiffness and numbness. Long-term slouching, head-down posture, incorrect sleeping positions, and poor posture can all contribute to cervical spine disorders, causing symptoms such as shoulder and neck pain and stiffness.
