Hi, I'm new to this forum. I had a discectomy 7 days ago Jan 24th 2012. I woke up pain free. I had severe l5 nerve root pain running down my legs. Since the surgery I have been walking 3 times a day for 30-40 mins pain free. I have however noticed some hip and glute tightness. Feels more tight mucsles in my hip but not sure. Also I have some slight numbness in the arch of my left foot which I did not have prior to surgery. I am really happy with how surgery went but am worried with what I have experienced! Am I over doing the exercise. My surgeon said I should remain active and walk lots.
