I had a lumbar laminectomy / discectomy on the L5-S1 around 8-9 months ago for some pretty painful sciatica shooting down my left leg from my gluteal region. I was doing pretty well until last week, and noticed that I had some sensitivity behind my outer left knee. The sensitivity is not debilitating, but really notable. Could I have possibly re-herniated? or can this be corrected? I have not had any pain yet from my gluteal region nor my lower back.

I have just started my gabapentin treatment again, I also had an occurrence today when I coughed and my upper left gluteal region issued me some sharp pain. Am I experiencing a recurrence of a herniated disc again?
