It is possible for a herniated disc to cause dizziness, but the disc here is specifically the cervical disc, and a herniated disc in the lumbar spine will not cause dizziness. There are two main pathological mechanisms by which a cervical disc can cause dizziness: 1. It is a herniated cervical disc that does not directly cause dizziness but induces dizziness in an indirect way. For example, when a cervical disc is herniated, it may produce a series of discomfort symptoms in the neck, upper extremities, and shoulder and back. If the disc protrudes forward, the sympathetic nerve in the front of the cervical spine will be compressed and stimulated, resulting in a series of head symptoms such as headache, migraine, blurred vision, memory loss, poor sleep, dizziness, ear swelling, etc.
