What has your surgeon said with regard to your increased weakness?
After my 2nd discectomy which was on L4 and it failed my legs were very weak for quite some time and shaky when I tried to walk. Maybe for the first two months. Then again I had severe burning pain in both legs and horrific back pain so I wasn't up and about much at all.

My disc bulge was small tho I was told a large amount of disc was removed during a percutaneous discectomy.

With time my legs felt stronger.

I too hope Mark can shed some light on your situation and hopefully your surgeon will have an explanation. Maybe further diagnostics are in order?
