Can a pinched nerve cause harsh lower back pain that runs down the left bum & leg , bladder pain, femoral pain and fever?

Polyradiculopathy : A pinched nerve in the low back can commonly cause back pain as well as pain in the lower extremity ("bum", leg, femur, etc.). If the femoral pain is in the front of the thigh, it is likely multiple nerves are irritated at the same time. "bladder pain" and fever may be due to a separate entity such as a uti. However, spinal cord infection & cauda equina syndrome must be ruled out->an emergency.
