This patient first came here 6 months after having an open microdiscectomy done elsewhere. He was complaining that his pain and numbness were worse than before the surgery.

He wanted to know if the small endoscopic procedure could be done for him now.

The answer is "no", he does not have a disc herniation now and the permanent changes caused by the open surgery (shown below) can not be reversed. He should have had the herniated disc treated endoscopically at the start.
