Cervical disc herniation, c3 herniation may cause dizziness, vomiting, or numbness of both upper limbs, weakness and other symptoms. 1. Dizziness and vomiting: The herniated disc may stimulate the vertebral artery on one side, leading to spasm and narrowing of the lumen of the vertebral artery, which in turn leads to insufficient or interrupted blood supply to the brain, resulting in dizziness, nausea, vomiting and other symptoms. 2. Symptoms of both upper limbs: patients with cervical disc herniation and c3 herniation may suffer from numbness, coldness and weakness of both upper limbs due to the compression of brachial plexus by cervical discs, which is often aggravated by exertion and cold. If the above symptoms occur, you should consult a doctor in time and take appropriate treatment under the doctor’s guidance to avoid delaying the condition. At the same time, usually need to pay attention to avoid bad sitting posture, appropriate activities, avoid exertion.
