Tarsal tunnel syndrome is a condition that occurs from abnormal pressure on a tibial nerve and it’s branches in the foot. It is similar to carpal tunnel syndrome in the wrist. There are many causes including inflammation, swelling, varicose veins, tumors etc. In many cases, doctors aren’t sure what causes tarsal tunnel syndrome. Inflammation in the tissues around the tibial nerve may contribute to the problem by causing swelling in the tissues and pressure on the nerve. Tarsal tunnel syndrome usually causes pain in the sole of the foot and about the inner ankle.. It is often associated with a burning or tingling sensation. These symptoms tend to be made worse by activities such as standing and walking for long periods. If the condition becomes worse, you may experience numbness and weakness in your foot. You doctor may choose to x-ray your foot or order nerve testing if she suspects this condition. There are many non-surgical treatment options including anti-inflammatories, cortisone injection, orthotics and physical therapy. If your symptoms fail to respond to nonsurgical treatments, surgery to relieve the pressure on the tibial nerve may be suggested.
