Could a micro discectomy bring positive results?

Yes. In the proper scenario, a microdiscectomy can be very helpful. Disc herniations can cause pain, numbness and weakness. If the symptoms have not gone away with conservative modalities, such as anti-inflammatory medications, physical therapy, epidural injections, then surgery is a good option. The procedure takes out the herniated portion through a small incision.
