Answer:
Pain radiating down the posterior thighration
Explanation:
A herniated intervertebral disk may compress the spinal nerve roots, causing sciatic nerve inflammation that results in pain radiating down the leg. Slight knee flexion should relieve, not precipitate, lower back pain. If nerve root compression remains untreated, weakness or paralysis of the innervated muscle group may result; lower leg atrophy may occur if muscles aren't used. Homans' sign is more typical of phlebothrombosis.
