Dizziness and numbness due to cervical spondylosis may be due to compression of the spinal cord and insufficient blood supply to the brain. In this case, surgical treatment is required, such as bed rest, relieving the compression of the spinal cord, applying relevant medications, and physical therapy. The specific treatment measures are as follows: 1. Bed rest. After the onset of the disease, the patient should first be made to adopt the supine position and continue bed rest for about 1 week. During this period, the patient should not be allowed to get out of bed. 2. Surgical treatment. For this type of patients, elective surgical treatment is needed. For example, anterior cervical spine surgery is needed to remove the protruding disc, and bone grafting and internal fixation of the adjacent vertebrae are carried out. 3. Application of relevant drugs. After the operation, some anti-inflammatory, anti-swelling and peripheral nerve nourishing drugs should be applied to these patients, such as prednisone, mannitol, methylcobalamin and other drugs. 4. Physical therapy. When this kind of patients are in the recovery period, they can be treated with physiotherapy such as hyperbaric oxygen in order to promote the recovery of related nerve functions. It is recommended that patients should go to the spine surgery in time when the above symptoms occur.
