Tightness in the neck may be a result of cervical spondylosis. This is a disease based on degenerative pathological changes. Long-term cervical spine strain and cervical disc prolapse can lead to compression of the nerve roots in the cervical spinal cord, resulting in neck muscle tension and neck pain, as well as symptoms such as upper limb weakness, dizziness and nausea. In this case, it is necessary to pay attention to rest, avoid bending and working with the head down, and pay attention to the cold and warmth to avoid getting cold. In addition, appropriate hot compresses can be applied to promote local blood circulation and relieve the symptoms of neck tension. If the neck pain is obvious, you need to take some oral anti-inflammatory and pain-relieving drugs, which can relieve the symptoms of pain, and you can also take some oral Chinese medicine to activate blood circulation and remove blood stasis. If the symptoms are still not relieved, you need to go to the hospital for further examination, you can check the MRI of the neck to clarify the diagnosis and carry out targeted treatment.
