Tarsal tunnel syndrome is a condition caused by repeated pressure that results in damage on the posterior tibial nerve. Your tibial nerve branches off of the sciatic nerve and is found near your ankle.
The tibial nerve runs through the tarsal tunnel, which is a narrow passageway inside your ankle that is bound by bone and soft tissue. Damage of the tibial nerve typically occurs when the nerve is compressed as a result of consistent pressure.


SYMPTOMS

• Severely flat feet, stretch the tibial nerve
  
  
• varicose veins in the membrane surrounding the tibial nerve
  
  
• inflammation from arthritis
  
  
• lesions and masses like tumors or lipomas near the tibial nerve
  
  
• injuries or trauma, ankle sprain, fracture inflammation and swelling

A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with fallen arches can produce strain and compression on the nerve.

An enlarged or abnormal structure that occupies space within the tunnel can compress the nerve. Some examples include a varicose vein, ganglion cyst, swollen tendon or arthritic bone spur.

An injury, such as an ankle sprain, may produce inflammation and swelling in or near the tunnel, resulting in compression of the nerve.

Systemic diseases, such as diabetes or arthritis, can cause swelling, thus compressing the nerve.

Core Clinik help improve foot stability by supporting the arch and reducing biomechanical stress in the area. Activity modification, calf stretching, and nerve mobility or gliding can help alleviate the symptoms.
