In 2010 I had surgery on L5-S1 and right leg was numb after surgery, not before. Pain still there sent me too PT for a few months nothing helped at all. Then I started back to pain clinic for the same relief I had , had prior to surgery and none of the injections helped either. After 2 years my right leg still numb, pain still bad I changed doctors. Day 1 the new doctor in 2013 told me that the screws were on my nerves chewing the nerve up and I needed surgery to repair L5-S1 revive , so in Jan 2014 almost to the day I had my new surgery. I learned from the new doctor that if a patient wakes up with a numb leg after surgery that wasn't numb before they should have done surgery right away to fix. And no I didn't sue, I'm still asking myself why I didn't. I'm still in a great deal of back pain and the foot pain is off the charts. I take pain pills mostly for back. I take Lyrica and cymbalta for feet also pain pills I also get RAN injections and I have a pain stimulate in my back. And still have pain. Since 2010 I've tried a great deal of things acupuncture for feet, shots of vit 12into my feet ouch I tried creams and lotions holistic doctors. I currently see a neurologist that also has the same condition and he is most worried about my feet numbness. Charlotte
