Hand numbness caused by cervical spondylosis is mostly caused by cervical spine osteophytes or herniated discs that compress or stimulate the nerve roots of the cervical spine. It can be relieved by adequate rest, medication, traction therapy and other treatments, and can also be treated with neurotrophic agents and neuroinflammatory response blockers, and if it still fails to be relieved, intervention or surgery can be considered for improvement.
