Is tarsal tunnel syndrome similar to carpal tunnel syndrome?

Yes, the two conditions have very similar causes and symptoms.  Both involve restriction of a pathway that a nerve follows to reach the end of a limb, in the case of tarsal tunnel it is the route the nerve takes into the foot from the leg, and in the case of carpal tunnel syndrome it is the route several nerves take to enter the hand from the arm.  Symptoms of the restriction and pressure against the respective nerves are the same, and can include numbness, burning, tingling, and general pain.  Treatment is also similar, involving either anti-inflammatory measures, therapy, or surgery to release the restriction.
