Lumbar disc herniation for more than 20 years can be recovered through treatment if the condition is mild and the individual is in good physical condition, but if the condition is severe and the individual is in poor physical condition, it is generally more difficult to recover completely. Lumbar disc herniation is due to degenerative changes in the annulus fibrosus, which is prone to rupture, and the nucleus pulposus protrudes in the middle, thus compressing the neighboring nerves and giving rise to lumbar pain and other symptoms. If the disease has lasted for more than 20 years, but the condition is mild, it can be recovered through bed rest, physical therapy, lumbar traction and medication. If the condition is serious, the annulus fibrosus is completely ruptured, the nucleus pulposus in the intervertebral disc protrudes into the spinal canal and causes stenosis, which seriously affects the quality of life, then it is necessary to take surgery to remove the nucleus pulposus and other treatments, which can alleviate the condition, but it is difficult to achieve a full recovery. In case of prolonged lumbar disc herniation, it is recommended to consult a doctor as soon as possible for relevant examinations to clarify the extent of the condition and standardize the treatment under the doctor’s guidance.
