The main cause of blocked ear sensation in cervical spondylosis is due to insufficient blood supply of vertebral artery, which is commonly seen in vertebral artery type cervical spondylosis. Treatment mainly includes physical therapy and medication. 1. Physical therapy: Physical therapy mainly includes cervical braking, heat therapy, traction, massage and so on. In the early stage of symptoms, cervical brakes can be used to prevent excessive movement of the cervical vertebrae from aggravating the symptoms; at the same time, other physical therapy methods can be used to accelerate blood circulation, widen the intervertebral space, and alleviate the symptoms of localized compression. 2. Medications: Commonly used medications include nutritive nerve drugs, vasodilator drugs, and edema-reducing drugs, such as methylcobalamin, vitamin B12, flunarizine hydrochloride tablets, mannitol, etc., which are mainly used to nourish the damaged nerves, increase the blood supply of vertebral arteries, reduce edema, and alleviate the symptoms of compression. If the symptoms of cervical spondylosis ear blockage are not relieved, or accompanied by other symptoms, you should go to the hospital in time to see a doctor, and give targeted treatment after clarifying the cause.
