Tarsal tunnel syndrome (TTS), also known as posterior tibial neuralgia, is a painful foot condition in which the tibial nerve is impinged and compressed.
Patients complain typically of numbness in the foot, radiating to the toes, pain, burning, electrical sensations, and tingling over the base of the foot and the heel. Some of the symptoms are:
- Pain and tingling in and around ankles and sometimes the toes
- Swelling of the feet
- Electric shock sensations
- Pain radiating up into the leg, and down into the arch, heel, and toes
- Hot and cold sensations in the feet
- A feeling as though the feet do not have enough padding
- Burning sensation on the bottom of foot that radiates upward
- Pins and needles and increased sensation on the feet
It is important to attempt to determine the source of the problem for effective treatment. Anything that creates pressure in the tarsal tunnel can cause TTS. This would include benign tumors or cysts, bone spurs, inflammation of the tendon sheath, nerve ganglions, or swelling from a broken or sprained ankle. Varicose veins (that may or may not be visible) can also cause compression of the nerve.
TTS is more common in athletes, active people, or individuals who stand a lot.
