After 8 months of severe pain, I am 5 weeks out of having discectomy on my L4/L5. I was feeling pretty good last week so I started physical therapy and now the sciatica is returning. Pain isn't severe like before but I don't want to irritate it again. Is this normal or should I stop doing the exercises my PT wants me to do? Anyone else have a similar story? It is scary to think this could all be starting over again .
