The speed of disappearance of numbness after lumbar disc herniation surgery depends on the degree of the patient’s lumbar disc herniation and the length of the herniation, and is also related to the patient’s own age and concomitant diseases, including diabetes and hypertension. Usually, after lumbar disc herniation surgery, the numbness will gradually disappear in 1-3 months; patients with severe lumbar disc herniation will take more than 6 months to recover. Numbness is a subjective experience of the patient and does not affect the patient’s life. Patients should pay attention to back pain and lower limb pain related to the quality of life, as well as the recovery of lower limb muscle strength.
