question: I have been trying to figure out why my legs are hurting so much, about an 8-10. Also my knees are hurting and are swollen all the time lately and are week, they give out a lot. I m recoding from thoriac back surgery, my surgeon cut a couple of chunks out and straightened my spine then fused from T8 to L1 were he tied into the 14 screws he placed while fussing L1-my sacrum in 2009, I now have 26 total screws. I m wondering if I injured my femoral nerve because my groin and inside of my legs hurt all the down to my ankles, along with my knee and leg pain?
