I was in a car accident almost a year ago with a broken pelvis. These past few weeks I've noticed some tingling and burning in knee and down my shin. As in sit here there's a bit of tingling on my left buttock. I had a microdiscetomy in October of 2016 for a herniated disc in my lumbar spine. My question is, would the blunt force trauma to my left side and fractured pelvis reinjured my lumbar spine creating another pinched nerve?
