Low head for a long time dizziness should be considered due to the following main reasons: First, low head for a long time, or often low head, can cause soft tissue strain on the neck muscles, fascia, ligaments and other soft tissue, sterile inflammation, soft tissue inflammation can stimulate the sympathetic nerves in the neck, causing spasm of the vertebral artery in the neck, which in turn leads to insufficient blood supply to the brain and dizziness. Second, low head for a long time neck strain, cervical spine small joint misalignment, stimulation or compression of the nerves and blood vessels in the neck, resulting in insufficient blood supply to the brain, eventually causing dizziness. Third, long-term low head, cervical spine osteophytes, herniated discs, cervical spinal stenosis, compression of the nerves, blood vessels and spinal cord in the neck cause dizziness.
