burning balls with numbness (both feet)

Posted by Doll on 7/08/01 at hrmin (052505)

Since an extended flight last year, I have had burning and numbness in both feet, primarily in the balls and very numb in large toe and some other toes. One foot has a large heel spur, but there doesn't seem to be relationship between the two.

Hi Doll,
Your symptoms are suggestive of tarsal tunnel syndrome. Tarsal tunnel and carpal tunnel are very similar conditions, so let's draw some parrallels.
With carpal tunnel, you have an entrapement of the nerve in the wrist as it passes under a ligament. Same holds true with tarsal tunnel. The posterior tibial nerve becomes entraped under several structures as it goes by the ankle into the foot.
Here's a simple test called a Tinel's Sign. It's a test that can be used for both carpal and tarsal tunnel syndromes. Let's assume your symptoms are in the right foot. Sit in a chair with your right foot crossed over your left knee. Find the medial (inside) ankle bone (it's called the medial malleolus). The posterior tibial nerve runs from the leg to the foot just behind the medial malleolus. Now use two of your fingers to percuss or tap, with mild to moderate firmness, that space on the inside of the heel jsut behind the medial malleolus. Do you get some tingles down into the toes? That would be a positive tinel's sign and very suggestive of tarsal tunnel. There's a good article on how to differentiate tarsal tunnel from PF at http://www.myfootshop.com .
