Paresthesia and pain on the plantar surface of the foot are common symptoms Other causes of tarsal tunnel syndrome: Space-occupying lesion within the tarsal tunnel (eg, a ganglion, synol cyst, or lipoma) or distally against one of the two terminal branches: the medial or lateral plantar nerve Trauma to the lower extremity Severe venous varicosities Tenosynovitis Tumor within the nerve Traction neuropathy in excessively valgus hindfoot position Ref: Clinical Neurology of the Older Adult edited by Joseph I.
