People with lumbar problems must have cervical problems, but people with cervical problems may not have lumbar problems, so a comprehensive examination is more conducive to treatment.
If it is a unilateral cervical vertebra problem, the headache should be that the nerves are compressed, leading to headache and dizziness.
If there is also a problem with the waist, it is necessary to treat both the waist and the cervical spine at the same time, so that it can be cured.
Personal advice, for reference only, or suggest that you find a hospital to systematically check your waist and cervical vertebrae for better treatment, early treatment and early recovery.
Personally, I suggest that you can buy a cervical pillow and lie flat for more than half an hour before going to bed every day, which can alleviate cervical spondylosis to some extent.
