Cervical C5C6 disc left posterior bulge refers to the left posterior herniation of the disc in the fifth and sixth segment of the cervical spine. According to the clinical symptoms and the degree of nerve compression, you can choose cervical traction, medication and surgery. 1. Cervical traction: It is suitable for mild cervical disc herniation, and can be chosen to increase the cervical spine gap and reduce the symptoms of nerve compression. 2. Medication: Non-steroidal anti-inflammatory and analgesic drugs such as ibuprofen and diclofenac sodium can be taken orally, as well as nutritive nerve drugs such as methylcobalamin and vitamin B12 to alleviate the symptoms of nerve irritation. 3. Surgical treatment: If the effect of conservative treatment is not good or the clinical symptoms are obvious, patients can choose surgical treatment, such as discectomy, disc implant fusion, etc., in order to relieve the symptoms of nerve root compression. Patients with cervical disc herniation should maintain correct sitting posture, avoid prolonged head down, etc., and can also bring neck brace to protect the cervical vertebrae. It is recommended that the patient actively cooperate with the doctor to standardize the treatment. The above medication should be used under the guidance of a doctor.
