What is carpotarnal syndrome?

Carpal tunnel syndrome is a condition in which the median nerve becomes compressed in the carpal tunnel, a narrow passageway in the wrist that connects the forearm to the hand. The median nerve controls the movement of the thumb, index finger, middle finger, and ring finger. When the median nerve is compressed, it can cause pain, numbness, and weakness in the wrist and hand.

Carpotarsal syndrome, on the other hand, is a much rarer condition that affects the tarsal tunnel, a similar passageway in the ankle. This passageway surrounds the tibial and peroneal nerves and connects the calf muscles to the forefoot. When this passage becomes inflamed or swollen, it can compress the two nerves, leading to:

- Pain or tingling sensation at the back of the ankle or in the arch of the foot

- Swelling in the ankle

- Difficulty walking

- Weakness or numbness in the toes

- Difficulty turning the foot inward or outward

- Inability to raise the foot upward
