Sensory loss and dysesthesia of the sole and dorsum of the foot and lateral leg are common. The ankle jerk is usually depressed or absent. In severe sciatic neuropathy, weakness of hamstrings (knee flexion) and triceps surae (plantar flexion) are also present. Weakness is commonly manifested as a foot drop, which results in a diagnostic challenge as sciatic neuropathy may imitate a fibular neuropathy at the fibular head or an L5 radiculopathy. Foot pain and dysesthesia are common and major symptoms in most patients. Sciatic neuropathy presents, usually acutely, with foot weakness, pain, and sensory loss ( 111). Clinical manifestations of sciatic neuropathies can be similar to fibular neuropathies.Signs and symptoms of sciatic neuropathy include foot drop, foot pain, and foot numbness.
