I am to sorry to hear about your problems. There are unfortunately limited treatment options for a post-laminectomy complication, especially one that occurred more than a decade ago. Most medications for neuropathic pain (pregabalin/TCAs) work through similar mechanisms, so if they have not worked for you in the past, I doubt that they will be effective at present. If you have learnt to live with the pain, then I would advise you to avoid trying medications as much as possible (unnecessary risk of drug side effects). If you feel that your quality of life is still significantly impaired, spinal cord stimulation (SCS) is a relatively newer treatment modality but with limited evidence and experience, so I would consider it only as a last resort.
