When the herniated disc compresses nerves, it will cause a series of symptoms and seriously affect the patient's quality of life. The following is a detailed analysis of the symptoms, relevant data, and treatment recommendations for nerve compression by the lumbar process.

1. Common symptoms of lumbar process compressing nerves
