Yes: There are many physical signs of nerve root compression and not all have to be present to raise suspicion. Straight leg raise, flexion, extension, side to side flexion are some. Other concerning findings are radiating pain down the leg, weakness in particular muscles, numbness or tingling in particular areas. Diagnostic tests that can of benefit include a emr, MRI or diagnostic injection.

Yes: Provocative tests like straight leg raises may be negative in some people or when the disk herniation is in certain locations (like lateral recess).
