Tarsal Tunnel Syndrome, similar to Carpal Tunnel Syndrome of the wrist, is a condition that occurs as a result of pressure on a nerve in the foot. This compression causes pain and discomfort in the foot, especially when walking.
The tarsal tunnel is the canal that extends between medial malleolus (the bump on the inside of the ankle) and the flexor retinaculum (the ligaments that extend across the foot). Inside the tarsal tunnel are the nerves, arteries, and tendons that provide movement and flexibility to the foot. One of these nerves, the tibial nerves, is responsible for providing sensation to the bottom of the foot.
This nerve can become compressed as a result of several factors, including:
- Flat feet or fallen arches
- Ankle swelling that compresses the nerve
- Arthritis of the foot that causes swelling
- Swelling as a result of diabetes
- Bone spurs or swollen tendons
Signs and symptoms of Tarsal Tunnel Syndrome may include:
- Pain in the foot
- Burning or tingling in the foot
- Numbness in the foot
